Re other poets/literary types who dug jazz, Philip Larkin and Kingsley Amis come to mind. Both were pretty mouldy figs, though Larkin was known to cut a caper to (New Testament) Basie. Amis, though, condemned himself (IIRC in his novel Take a Girl Like You) by including in his cricket team of 11 Villains none other than John Coltrane. Amis was clearly happier with Condon (Eddie, not Les).
