Memories about growing up in:

1968 poster of Janis Joplin at the Rainbow Ballroom. It was about this time that my neighbor was telling me that all the girls stood with their hand, palm down and covering their drink cup - to prevent a pill being dropped in. Known back then as a "mickey"

I lived in Fresno in the early 70s,and what I remember about the Rainbow ballroom was a good time.
All of the cool bands played there. Tower of Power , Bobby Womack. On one show there was the Dramatics, the Dells, the Delfonics and New Birth.
At that time it was more of a nightclub feel.
