Cochabamba Candle Choir (Vancouver)

Yet another obscure Light Show from Vancouver, this time from 1973 which is right on the edge of the 'Death of Light Shows' as they (sadly) gave way to conventional Stage Lighting.

Can you help with any information about Cochabamba Candle Choir? All we have is this one poster below from The Moose Hall.

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

Fireweed, Ambleside and O'Dain at The Moose Hall, Saturday January 20th 1973
