Mr. What and his Colour Circus (Santa Clara)

We previously had this Light Show incorrectly named and also had a double entry due to my stupidity but the mistake has now been rectified (not that anyone would have noticed...).

We believe they were from the Santa Clara area and have only seen them listed on this one poster below but there was also reference to them as being members of The Lightshow Guild in The Berkeley Tribe during 1969.

Can you help with anymore information about Mr. What and his Colour Circus?

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