Indeed they are! BBC4 listings for Saturday 18 April:
8.00 Legends: The Charlie Parker Story
9.00 Film: Let's Get Lost
11.00 The Jazz Baroness (repeat of previous evening's documentary)
12.25am - 1.10 Imagine: Saint John Coltrane
Probably the work of the guy who cancelled today's JRR to make way for opera.
P.S. Delighted - and surprised - to see in today's Guardian a leader on the theme of "stop messing about with Jazz Record Requests. Recognition at last!
I'm reading Study in Scarlet now, having started with The Adventures .... I think Holmes is ideally suited to the short story form and that Doyle hadn't yet fully found his way when he wrote Study.
