Doc, did you see the Cream reunion on PBS a year or so ago?? Clapton, Baker, Bruce singing a ton of the old Cream songs.
And, they sounded GREAT! To me, one of the greatest sounds in rock music: a big wall full of the Marshall amps, with Clapton's wizardry blasting your wig off! And, Baker sweating his butt off, working like a dog on the double bass drums. Jack's voice was a little wobbly, but good enough.
If you're a fan of any of those guys, or of R&B music, you've GOT to catch that PBS broadcast. I had it running through my stereo system, darn near blew the roof off my TV room when "Crossroads" came on!
Great stuff. I think Winwood did a few tunes as well. The white Ray Charles, they called him.
