Yes. BTW, tomorrow is the 67th anniversary of the Million Dollar Quartet. On 12/4/56, there was a jam session at Sun Studio in Memphis. Elvis, Johnny Cash, Carl Perkins, and Jerry Lee Lewis got together, while Sam Phillips rolled tape. That session was immortalized in the Broadway play with the same name.
We went to a tribute/cover band rendition of that event about 6 months ago. It was fun.
