Ha ha. I don’t expect everybody to know Larry because his era had been swallowed up a lot by all the fads that came after but, yes, he was a major land mark in that genre.
I did gigs with him at places like Pizza on the Park and Cleo Lane’s place in Wavendon. I’d get there early just to sit and listen to Larry’s stories. He’d talk about being in a jeep in Italy during WWII with Lauren Bacall(oh yes) and bullets flying everywhere. 
He had stories about growing up with the Gershwins too.
Great guy, amazing musician(you had to keep on your toes as he could change his mind about numbers IN THE MIDDLE OF THE GIG!!!)!
Hair raising but worth every second.
