Don't know what the hell happened but I spent a great deal of time researching my correction to this post and now it is gone. Here is a short summation.
In the '70s BN issued a 2 lp set called Back From The Gig under Ervin's name. It included the "soon to be released" material (Ervin, Woody Shaw, Kenny Barron, Jan Arnett and Billy Higgins) AND a Horace Parlan date reissued on cd as Happy Frame of Mind with Ervin, Johnny Coles, Grant Green, Butch Warren and Higgins.
