TJS lists a JGB show from Monday, 1/26/76, Keystone, Berkeley. There's a really nice unattributed photo captioned with this date there, as well.
But Corry's old lists had the first show of the Keith & Donna era as 1/27/76, so I am wondering what is the basis for the 1/26 listing. Gordon Sharpless, if you read this, can you shed any light? You are listed as a contributor at TJS.
For that matter, Corry, can you shed any light on the 11/4/78 listing as the last one of the K&D era?
