I'll bet you had fun. In 1976, some friends and I spent $3.50 each for tickets to the "A Star is Born" concert in Tempe, AZ at Sun Devil Stadium. The cast of characters who performed were Montrose, Santana, Kris Kristofferson, Babs (yes, she had a foul mouth even back then), Peter Frampton, and some others whose names I don't recall. We were there from 5:30Am to 5:30PM.
Wow, Talk about living dangerously....Montrose and Santana with Kris and Babs...What a mix. Almost as bad as Eddie Money opening up for ZZ Top ack in te early 80's..
