A tape in the Joe Brazil collection labeled "Thad Jones at the West End" contains an announcer saying, "How about a hand for Thad. Thank you, Freddie Froo. Freddie Froo on the drums, Joe Brazil on the alto, Ernie Farrow on the bass and Abe Woodley on the piano."
According to an article at http://www.telegram.com/article/20121119/NEWS/121119571, Freddie Froo was a nickname for Detroit drummer Fred Metcalf. Baritone saxophonist Pepper Adams wrote a song for him.
Abe Woodley also worked in a band called the Jazztet with Joe Brazil.
According to Before Motown, the West End Hotel was a popular Detroit location for weekend after hours jam sessions in the late 1950s.
Thanks to the owner of the Joe Brazil tape collection for allowing me access to this rich trove of historical information.
