George Harrison played with many associates of both Dylan and the Stones. Bobby Keys was one of the most renowned sax men of rock and roll, Nicky Hopkins contributed to the buzz of "Revolution", and Jesse "Ed" Davis had his fingerprints all over early seventies solo Beatles. This week, we consider some recordings, most made at Apple Studios, most featuring George Harrison on electric (usually slide) guitar. Who knew George could compose Mexicali blues (as some call "The Holdup")

More of Paul McCartney and his political notions. Animal Rights, Gun Violence, "No More Landmines", and the environment have been a big part of the "McCartney brand" for the last 30-35 years. We continue from last week, as we touch on nearly a full album of political thought from "the cute Beatle", and how Paul's brand of radicalism was both similar and different to that of his bandmate John Lennon.

Following on from "One to One", Martin and I spend this week and next discussing the politics of Paul (and Linda) McCartney. This week, the Beatle years. How Paul brought John into the peace movement (and possibly why he deserves that credit on "Give Peace a Chance"), McCartney and Bertrand Russell, Blackbird, Commonwealth and on through the early solo years. Next week, a rundown on solo McCartney's political songs! #madeonzencastr
