This link was on another music board I belong to where we are having a nice conversation about it. Thought it would be interesting to see who we'd all bring back if we could.

I voted "other" for Benjamin Orr of The Cars and Brian Connolly & Mick Tucker of Sweet but of course I would want to see Freddie Mercury, Stevie Ray Vaughan, Jim Morrison, Jon Bonham, etc... back also.
