10. Dave Mustaine, first guitarist for Metallica. He left to form his own metal band, Megadeth. Perhaps not as much money in his pocket but at least he was his own man.

9. Tracii Guns, guitarist for Guns n' Roses. After not showing up for a rehearsal Tracii was replaced by Slash. Tracii formed another band, L.A. Guns, who have had some success but clearly nothing like G n R.

8. Chuck Mosley, and Faith No More, Chuck Mosley, who left the band because of 'creative differences' was replaced by Mike Patton . Chuck went on to front Bad Brains, whilst Faith No More flourished.

7. The Backstreet Boys, Burk Parsons quit to become a minister, one wonders if he ever looked back and thought - Oh Lord why have you forsaken me'

6. Dave Evans, the original singer of AC/DC Bon Scott replaced Dave Evans just before the band became huge. Dave went on to front the band as The Hot Cockerels and we all know how well they have done.

5. Seventy three drummers failed to make it with Nirvana. Nirvana had 73 different drummers, before Dave Grohl joined in 1990. Dave joined just as the band took off, pretty good career move you could say.

4. Ian Stewart, founding member of The Rolling Stones. Ian and Brian Jones co-founded the band. But somehow Ian just wasn't Rock n Roll enough and he was eased out of the band, managing them for a while and playing a bit of keyboards.

3. Glen Matlock, original bassist of The Sex Pistols Was Glen kicked out because he liked The Beatles too much, who really knows ? What we do know is that he is one of the great bassists and still gigs brilliantly today.

2. Syd Barrett and Pink Floyd However successful they were to later become these words are always seemingly linked. Syd the creative genius of early Pink Floyd, quickly became addicted to drugs and after bad LSD trips could no longer function adequately and became a total recluse and left the Band. A bizarre twist, many years later when they were recording the tribute to Syd you Shine On You Crazy Diamond, he apparently walked into the studio !

1. Pete Best, the original drummer of the Beatles Ditched by the Beatles just before real success, reputedly he was too good looking for the other members of the band but we have heard rumours about a liaison between Lennon and Bests mother which might have had something to do with it. Anyway definitely the unluckiest drummer in the World.

From Jack Black, to Jack White, who is seen taking up the mantle of Elvis Presley in this 2007 comedy. The White Stripes front man provides a dead-on performance, even grasping Presley's often inaudible mumble, love of "kur-a-tay" and a massive entourage supported ego. The estranged White shows his funny side, a side no-one knew existed, until now.

9. Jack Black - 'Anchorman: The Legend of Ron Burgundy'

Tenacious D's Jack Black stars in this cult comedy from 2004 as a vengeful biker who gets hit with Will Ferrell's flying burito, and proceeds to kick his dog from a bridge. A heartfelt, hilarious and classic film moment,that could not be missed from this list.

8. Dave Grohl, Meatloaf and Dio - 'Tenacious D: The Pick of Destiny'

This film is already rock and roll enough, but goes one step further, aiding the help of Dave Grohl, Meat Loaf and Dio. Meatloaf plays Jack Black's rock-hating Dad (obviously), Grohl plays Beelzeboss aka. The Devil and Dio plays, well, Dio. It's a fantastic performance from a rocking cast.

7. Jon Bon Jovi - 'U-571' This has to be my favourite cameo on the list, as it is sheer rockin' genius. One minute Jon's minding his own business on a ship, the next minute those pesky Germans go and sweep him overboard and he drowns to. It shouldn't happen to somebody who's seen a million faces and rocked them all.

6. David Bowie - 'Zoolander'

Who better to judge an intense walk-off between Ben Stiller and Owen Wilson than ultra-hip and glamorous David Bowie? It's easily the best scene in the film, seeing bowie accompanied by 'cool dude' Billy Zane.

5. Twisted Sister - 'Pee Wee's Big Adventure' Do I really need to say any more? No, but I will. Twisted Sister (flanked by lovely ladies) jack a car and play 'Burn In Hell' while Pee Wee Herman whizzes past on a bicycle. The great thing is, it has no connection to the film, and to be truthful, there is no need for the appearance to feature at all. Despite this, it is absolutely brilliant.

4. Bruce Springsteen, "High Fidelity" (2000) Rob Gordon (John Cusack) is obsessed with music and he can't seem to take the next step in his adult life. In the movie, Rob has a conversation in his head out loud with the Boss, Bruce Springsteen of course, who shows up strumming a guitar in the studio, to offer some sage advice.. "Thanks, Boss," he says, saluting after it's over. It kind of is, but shouldn't be, as funny as it sounds

3. Billy Idol - The Wedding Singer

How many washed-up 80s rockers get to save the day in a hugely popular romantic comedy? Since Adam Sandler's 'The Wedding Singer' takes place in 1985 but was filmed in 1998, that means Billy Idol was 43 years old playing himself at 29 when he showed up on that fateful plane ride with Sandler and Drew Barrymore. This appearance alone probably upped his nostalgic 'cool' factor for a good 5 years or so.

2. Alice Cooper - 'Wayne's World'

Cooper's appearance in this classic film comes at a point when the devious Rob Lowe gives Wayne and Garth backstage passes to Cooper's show. Cooper is decked out in leather and black eye make-up, of course, and drops Native American knowledge on the boys prompting them to respond "we are not worthy." Hilarious.

1. Keith Richards - Pirates of The Caribbean

This might be a controversial top choice, but you have to give it up to Keith Richards, who plays the awesome character of Captain Teague Sparrow, Johnny Depps dad. Aww. Though you would think his appearance would be more comedic (it's actually quite dramatic), it's still bloody good.
