Midge Ure (2)
Not that my vote would matter at this point, but... Yeah, I vote for Nirvana, too. I love Midge's version, but — like so many pointed out in the comments — Nirvana's has an emotional significance (and content) that's hard to match.
Thanks, everyone, for coming by to vote and comment, and my apologies for the late post with the results. I'm finally back in Dushi Kòrsou, happy to be home (and in good-wifi land :D ). I've missed you all.
