There is a company that bought all of the musical items from Bill Graham's estate called Wolfgangs Vault. They sell posters and memorbilia from the Filmore, etc. On their site they have a section called Concert Vault where they stream complete shows from the 60's and 70's that were recorded at the Filmore, Winterland, and other venues. One of the shows they have posted is a CC Riders show from April 1, 1971 (pre Jaco). You can listen to it here-
I don't know who's in the band. For most of the bands on the site it lists complete personnel, but nothing for the Riders. It sounds to me like Charlie Brent introducing Wayne at the end of I Want To Take You Higher, so I would presume the wild guitar solo on Instrumental Jam is him. Odd that the opening song is listed as Unknown when its obviously For Once in My Life.
