Don't know about jazz these days, but there were bitter arguments between the Trads and Moderns in the 60s (I was a Trad)

Ah - a "mouldy fig", eh...? Well, you could have been a "dirty bopper", I suppose. I remember those arguments. There was dear old Ken Colyer, bringing back the true Bunk Johnson sound from New Orleans, while Benny Green and Ronnie Scott were bopping away in Gerrard Street.

Wasn't there a Federation of Jazz Clubs somewhere around then as well? Died a death like all such things, as I recall.
