Another Shaggs / Shags

From the blog post, I read that Chuck formed his own Shags in Peoria. He enrolled at Notre Dame University and joined the existing Shaggs (2 G's) when their lead singer. This is the group that recorded the two songs for the acetate.
Chuck didn't rejoin the Peoria group that isssued a pair of 45s in 1967.
 
Hi, sorry to bother you after such a long time, are you talking about these Shags/Shaggs?
P.S. I am/was the maker of the five "A Journey to Tyme" and the two "Sounds of The Sixties - San Francisco Part 1&2" back in the 80's CIMG5892.JPGCIMG5896.JPG
