I admit that I wondered for half a second about the guitar, and even thought maybe Albert Lee, as he is on that London record. I then realized who asked the question, which will be my only hint at it.
I am not aware of Carlo gigging with the Killer, but maybe he did. The guy I am thinking of is on several hits, and also recorded with Jerry Lee. Like the mystery guitarist, and Carlo, he drummed along with a Gibson or Epi bass in the 60s. I will spill said beans tomorrow.
Until then, I will spin the wonderful lp Soul My Way, which I recommend to all!
