It's also on Fresh Sound 357, at least the 2004 version I've got.
Another question though: at the end of just that track, "Lester Left Town" (CD2#1), someone (dee jay?) is heard stating that Walter Davis Jr. was sitting in on piano for Bobby Timmons that morning... which implies Timmons was absent that day, hence Davis would also play on the other tune from that June 4, 1960 date, "The Midget" (heard on CD1#3).
But that doesn't seem to be noted anywhere...
