Well, he still could release one, one day. For years people wondered if he was going to release a 'best of' and he finally got around to it, so a live album could still see the light of day in the future.

I know I read once in one of his interviews where he joked about it, saying that he has a lot of his shows taped, just in case he ever got hit by a bus there'd be enough material to do a posthumous (sp?!

) one.
(btw, speaking of the 'Best of' here's a belated Christmas present for Chris - his album re-entered the top 20 chart down here in Aus. over Christmas and got as high as No. 15 again...it's currently sitting pretty at 19.)
