This clip is historic. Carl Perkins, George Harrison (who snagged/developed Carl’s licks to make his own sound), Eric who played with Carl during a Derek & the Dominos set on the Johnny Cash Show (YouTube it), Dave Edmunds, Ringo, cats from the Stray Cats, & Rosanne Cash.
The joy on their faces says it all! And George in awe, having the time off his life, looking at Carl for Daddy’s approval. And he got it! Thx for the upload!
