There's a strange and giddy thrill that accompanies spotting a famous person outside of the environment for which they're known. "Hey, what's Jerry Seinfeld doing off stage?" / "Is that Joe Pesci buying underwear?" / "and what's Christian Slater doing knee deep in my septic tank?". The same is also true of cameo roles; those amusing walk-on bits that see celebrities of all ilks cross paths with some of the cinema's vast array of fictional creations.
Given the ongoing love affair between film and music industries it should come as no surprise that musicians make up the bulk of these unexpected appearances. Some have dreams of truly 'crossing over', while others are just in it for the giggles (and the buckets full of cash). In either case, these cameos usually end up being a whole lot of fun, case in point
