Chris Squire, founding member of progressive rock group Yes is 61 today. Yes has been through several incarnations. And at one point there were 2 distinct versions of Yes that came together for the album Union. It turns out, Squire is the only member from either version to have played on every Yes album. I've followed Yes since their inception. To me, though, their glory years were when the lineup included oragnist extraordinaire Rick Wakeman. Here's Roundabout from that period; from their 1971 album Fragile.
