By '67 I had moved on to work with several other groups and even had opportunities to play some rather large venues with several regional rock bands before 1970 when I left the music business. I still have a lot of memories that go along what that time in my life, some good, some bad, and some that still make me laugh out loud like the time I mumbled the entire first verse of "Proud Mary". We were preforming on the stage of a large high school auditorium with over a thousand people in the audience listening. I had a mind block and couldn't remember the words. The funny part is that no one seemed to notice including the band! I guess that was a good example of the fact that most people hear what they expect to hear.
One of the other "first songs" that I remember playing was with a band that was actually getting paid for gigs in '66. It was a tune by the Rolling Stones named "Off The Hook". Here's an early video featuring their performance of the song.
This video was recorded at the Santa Monica Civic Center:
