Nice response, Gheorghe.
I, too, was too young for this JATP session, as I didn't start listening till I was 17 in 1957. But, anyway, the British Musicians Union had a ban on visiting Americans at the time, though I seem to have heard that JATP got into Essex (?) in about '53 at an American airbase (?). (Someone will know about this.) The nearest Kenton got to the UK in '53 was Ireland and I've spoken to slightly older fans who made the journey. But at least I was early enough to see Jimmy Rushing and Hines with Teagarden (all in '57).
That album is a gas!
