Brownsville Station was a band from Michigan that was popular in the 1970s. One of its earliest hits (1970) was called "Bebop Confidential" with song writing credits given to band founder Cub Koda. However, Gene Vincent recorded it in 1956. The song was called "Be Bop a Lula". This is probably why BS omitted it from their various anthologies.
