Big Al, Bailey is the drummer on all the other "Confirmation" LP tracks. The 8/57 tracks were misidentified as Blakey. Art was not present at the August 25, 1957 session, but was the drummer for most of the February 25, 1958 session, only "Lover Man" featured Bailey on drums. The entirety of that latter session is contained on "The Sermon" and "Houseparty" RVG's. Also it is easy to hear the 8/25/57 tracks feature Bailey, as both drummers are very different and distinctive.
