I always cringe a little when I hear the words 'David Bowie' and 'covers' in the same sentance but surprisingly there are some good ones out there, what songs have you head that do the original justice?
For me I actually prefer Nirvana's 'Man Who Sold The World' on the Unplugged album, though I don't deny the original is great. But my favourite is 'Teenage Wildlife' by Ash - they totally nail it.
They are the only two decent attemps I can think of, I'm sure some of you have heard some competent efforts yourselves.
But if ANY of you say X-Factor's Heroes I will hunt you down and I will shoot you.
