I think his "A" group is Geoff Keyser (sp?) and some young drummer who looks about 19. I saw them a few years ago and they were absolutely killing. I saw him earlier this year with what i took to be his "B" group on a lower-profile gig. I can't remember the name of the sidemen off the top of my head, but I posted a thread on it down here in DB somewhere...I'm sure a search of thread titles with "Ray Brown" as the keyword would turn it up.
