Found a good series on the toob, recordings from Scottish TV, full programmes average 24 minutes each. Some hosted by Annie Ross of Lambert Hendricks and Ross, others by George Chisholm a great trombone player and Ronnie Scott.
I've not gone through the lot yet, but have found quite a few interesting guest appearances, example, Bob Brookmeyer, Buddy de Franco.
At over 20 minutes each it'll take a few days to pick over what's there.
A couple of examples

I notice some of the players in the band on the second season sessions featured in the Benny Goodman band formed for the UK and European tour in 1969, Lenny Bush on Bass, Tommy Whitle on sax, and George Chisholm on Trombone.
A few less usual instruments feature on some sessions, harp, tin whistle, accordion. Some vocals, a couple of jazz rock groups.
Highlights far me so far, a trombone duet George Chisholm and Don Lusher, Jimmy Feighan quartet (piano, vibes, guitar & drums) David Snell on harp, Lenny Bush's solid bass. Unusual pairing, George Chisholm (trombone) with Jack Emblow Accordion.
