Don Johns (Sonoma)

There was an event on July 1st, 1966 at the Petaluma Memorial Hall in Sonoma County, California that listed Don Johns doing lights with The Mystery Trend, The Final Solution, and Shadows playing but we do not know anymore about this Light Show, are you able to help?

A Handbill for the events exists and can be seen HERE

If you can help with more information about this Light Show we would love to hear from you.
