The PSR groups were started almost two years ago by Bob Gelman, who was a regular contributer to this group and the now-defunct Yamaha forum. It was mainly through Bob's efforts to get the ball rolling and keep everything running smoothly that the PSR groups became as large as they are. Earlier this year they became part of the Yahoo "family", but Bob is still the administrator.
I shamelessly boast of having the very first song posted on the Songs group.
