The Mar-Keys were the backing band on lots of early Stax records, and had personnel overlap with what became the MGs & The Memphis Horns.

Deanie Parker’s liner notes say “Booker T. & The MG’s . . . is the rhythm section of The Mar-Keys.” This album was recorded live on a Stax/Volt tour in Europe – some sources say this is from L’Olympia, Paris, France, March, 1967 – but I can’t find anything definitive. VMP just says “recorded during a European tour during the 1960s.”
