Wow, that's crazy, I just looked it up on Wikipedia, and they don't even list Strolling in his discography!

Considering it was released in 1965, it likely was John Levy, his bassist and manager through the 1960's, now that I read up on it ;-)

haha!!! Yeah, I saw that, I had a split second of thinking it must be a rare record!! .. its not!! haha! Yeah Levy was a don!!! Looks like it must be him!! thanks for that nugget of info!!! RESPECT!!
My pleasure! ...a bit of a learning experience for me too. I liked the Strolling vid on YT, it reminded me of Thelonius Monk's 'Well you Needn't', didn't think George went in that direction, but his career did span quite a bit ...
Look forward to hearing more from you. Respect back at ya!
