Alan Bates of Black Lion has the rights for all Fred Norsworthy produced Jazzline et.al. LPs, there was a CD of this issued in 1989 with three alternate takes added, Black Lion BLCD 760134, under Donald Byrd's (!) name, titled Groovin' For Nat. A nice session, the rhythm section with Pearson, Bob Cranshaw and Walter Perkins cooks, and the unusual two trumpet frontline is very attractive, nice to compare Byrd and Coles.
This will definitely not be part of the Mosaic Select, so look for this CD:
Thanks Mike!
