Just watched the History of the Eagles...had never heard of POCO and/Timothy Schmidt...until now. Also, Glenn Frey and Don Henley got their start from Bob Segur and Linda Ronstadt.
What I've been told over the years:
Linda Rondstat wanted to do a live tour but had no band. She went to the LA musicians hall and put together a group to go on tour with her...after the tour, the tour band essentially became The Eagles.
Linda was a founding member of the music group Stone Poneys that included Bobby Kimball who went on to become lead singer for TOTO.
Here's an example of TOTO with Kimball as lead singer: Hold The Line
(By the way, Linda shacked up with Jerry Brown the first time he was governor of California. Jerry wouldn't live in the governors mansion.)
I got the wrong link in my post #11 for bobby Kimball and TOTO, here it is:
BTY, the above link is from a TOTO concert where they are accompanied by a 50 piece orchestra and a 50 member chorus...fantastic music.
TOTO's song Rosanna was written about actress Rosanna Arquette and a TOTO band member... notice the 'West Side Story' motif in the video and the girl in the red dress in this video did the difficult dance parts in the movie 'Flashdance'.
It's all connected, eh?
