well i think the original premise is more fun...there are too many instances of someone taking an obscure song and putting their own twist on things, heck, Counting Crows just did a full CD of other peoples music. The thread as is, taking an established 'hit' and re-making it, that is a challenge for bands, to either copy it as close to the original or, like in the case of All Along The Watchtower, put their mark on it and make it a 'new' song...hell Clapton did it to himself with Layla, the original version and the MTV Unplugged version. I prefer the original thread idea.
