In response to John Jenning's mention of Rhoda Blount - she is at the Philadelphia Afro-American Cultural and Historical Museum, programming the music events. She coordinated the Arkestra tribute concert last October, at which I displayed my Sun Ra photos. During the second set she danced with the Arkestra. She said that she was not related to Sunny.
More recently she mentioned a concert early this fall (maybe a Coltrane tribute) with Archie Shepp and another tenor (?David Murray).
