Marty, have you seen any of the pics of Lindsey and Stevie when they were in The Fritz Reiner Memorial Band (original name, later shortened to merely Fritz)? They were just another local San Jose cover band, playing at local High Schools and Teen Centers like the rest of us. There are pics of her on stage in a Prom dress, with a bouffant hairdo! I saw them live only once, as the opening act at the Santa Clara (valley) Folk Rock Festival in the Summer of '68. Also on the bill were The Electric Flag (fantastic!), and The Doors, who closed the show.
Maybe it was San Jose's The Doobie Brothers getting a Warner Brothers record deal that inspired them to move to L.A. in '72 or so. They've done pretty well for themselves ;-).
