The latest craze on US telly seems to be demonstrating that the stars truly are all-singing, all-dancing buckets of talent - what with Hugh Laurie whipping out his guitar on House, and the cast of Scrubs bouncing their way through a full-blown musical episode, it seems there’s no end to their talents.

We’re all for it, especially if it means we get to see CSI’s Gil Grissom tap-dancing next season, or Dexter revealing an uncanny knack for ventriloquism.

The humble karaoke bar is one of the perfect venues for a bit of showing off in a show - here are some of our favourites, and a couple of golden oldies too. Feel free to add to our list.

Brothers & Sisters Sarah and Kevin strut their stuff. Kev, don’t give up the day job…

Desperate Housewives Susan puts her own spin on a Frank Sinatra classic.

Bones The normally sedate Bones shows she does know how to have fun. Ok, we know it’s not the real audio, but it seems the folks at Fox aren’t keen on anyone accessing that… (they don’t know how to have fun!)

Hugh Jackman Hugh appears on the regular karaoke slot on the Ellen DeGeneres show. Ellen, we salute you - you can get just about anyone to do just about anything!

And now, two old classics from Ally McBeal - the champion of impromptu singing - as Robert Downey Jr and James Marsden reveal their vocal talents.
