You know, there is no sign of "Mayfair" anywhere but the front cover. It's a British record - the back cover states A&M, distributed by Pye Records. The labels have A&M, CTI and Creed Taylor's signature printed on them. The liner notes are fairly brief, with no band line-ups mentioned. I do like side 2, the tracks from "From the Hot Afternoon".
Mine isn't this version, it's a British reissue from the 80s. Yet another player I've never previously heard, and probably wouldn't have bought.
