Of course, more promising (and with better reception) radio fare in those days was the Voice of America Jazz Hour with Willis Conover.
Radio Luxembourg with its Jamboree Jazz Time also deserves a mention - where I first heard Coltrane and Ornette (in the spring of 1959).
Around 1960 I used to listen to AFN radio from Germany, just about hearing the music through a mass of static. The things I used to do to hear jazz, which the BBC largely disapproved of!
On the theme of musicians listening to other musicians, a friend who saw the Gillespie and Coltrane groups in Newcastle upon Tyne in November 1961 told me that Trane sat in the audience during the Gillespie set and laughed his head off at Dizzy's clowning.
