What about the jam in “I Wonder” from the Smokin’ album. Also found an acoustic version of “For Your Love”. Marriott in rare form: https://m.youtube.com/watch?v=W0gkMzies2U
I'll see your "I Wonder" with C'mon Everybody and Sweet Peace and Time from "Smokin'" and I'll raise you Up Your Sleeve and Road Runner from "Eat It!"
