Listened to most of that Elmo show en route to Newark yesterday. It included an interview with Bertha Hope, who gave some fascinating and very erudite insights into the circumstances of the music. Bertha also did a very nice gig at the Marriott Brooklyn (solo and quartet) on Friday night which I was fortunate to catch (quartet - Bertha Hope, Roni Ben-Hur, Walter Booker, Leroy Williams). Too bad that there wasn't better attendance from the NYC area though.
Of particular note - that radio show also included an excerpt from one of Bertha's tapes of a club gig Elmo did back in 1958 in Vancouver with Harold Land, Scott LaFaro and Clifford Jarvis.
