Hi, WGV:   That Stoneground show from 1971 was very very welcome.   Too bad Lydia Phillips wasnt listed as being with the band this nigh-----becuase she was a 4th woman singer with the band at this time (1971).  PLEASE ADD HER TO THE BAND LINEUP for this show.   Lydia sang some show stoppin', hip shakin', face dancin', soul smilin' songs with the band.   They sounded so good live, and created such a happy SF rock & roll vibe.   Check out their 1st album if you can ever find it.   It rocks rocks rocks.
