I don't think so (oh, but yes, it's smokin! - my introduction to the jazz organ, this single). The personnel I have for this 45 is
Mack Johnson (tp)
David "Bubba" Brooks (ts)
Cornell Muldrow (org)
Phil Upchurch (g,el-b)
Joe Hadrick (d)
I don't know who Cornell Muldrow is but I don't think he's James Booker. (Hadrick, by the way, went on to become Willis Jackson's drummer and stayed with him until Gator's death. He was called Yusef Ali, on later Gator LPs.)

Joe Hadrick is who told me that Booker played that date. For some reason Cornell Muldrow didn't play the date. Muldrow was an organist from Baltimore (Joe's hometown) jand with the exception of Booker this was the backup band for Dee Clark.
Hmm.... Last night I had a 45 RPM listening session. At one point, I played the Boyd 45 of "You Can't Sit Down," followed by two of Booker's Peacock singles, recorded around the same time. This morning I picked out sections of the Upchurch record with prominent organ and compared them to parts of "Gonzo" and "Cool Turkey."
All I can say is that the organist on "You Can't Sit Down" doesn't sound like James Booker to me. Booker's sound is consistent on the Peacock records - he uses the drawbars to emphasize the higher harmonics. (I don't know what terminology organists use, so forgive my ignorance.) The organist on "You Can't Sit Down" has a very different sound - fatter and more "modern."
And since Muldrow has co-composer credit on the tune, it seems odd to me that he wouldn't have played on it. I don't know what else was recorded at the "Can't Sit Down" session - could Booker have sat in on some other tunes?
All this is based on my ears, of course, which have failed me before. But it doesn't sound like Booker to me.
Have no idea whether it's Booker or not but, from what I can find, all that was recorded at that session was "You Can't Sit Down Parts 1 & 2".
