Wouldn't sell my soul under any circumstances. Not that I actually believe in the concept of a soul, in the religious sense.
And from my old man perspective, I wouldn't want to be a rock star either. The broken relationships. The tedium of life on the road. Success and status gradually slipping away while you desperately try to cling on to fading youth and past glories.... (look at the likes of Ratt and Warrant :roll: )
But Adam.M makes a good point - if it was 1969 and I was 20 years old, then yes, I would love to be a rock star. At the cost of my "soul"... maybe not.
(Note: I wasn't 20 years old in 1969. I just think that would have been the best time to be around - at the right age. Imagine being a contemporary of Jimmy Page, Ritchie Blackmore, Leslie West, Paul Kossoff... :D )
