Lysergic Power & Light Company (San Francisco)

Yet another Bay Area Light Show we are looking for details on, are you able to help?

Great name (spelled Lyserguc) on some documents.

Only seen so far at the Bedrock One event - 05/03/1967 at the California Hall featuring Steve Miller Blues Band, Dino Valenti, The Orkustra.

Also on the bill were the Rada Krishna Temple, The San Francisco Mime Troupe and The Diggers.

Allegedly there are only a Blue and Pink variant of the Robert Crumb poster seen below so the top, yellow variant might turn out to be an 'internet fake' unless you know more?

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