40 years with the white album
There's an interesting look back at the White Album on the All Songs Considered podcast: 'The White Album' 40 years later - with all sorts of interesting tidbits (Paul McCartney plays drums on 'Back in the U.S.S.R' after Ringo leaves the studio in a huff), recordings of practice sessions and songs that didn't make the cut. The podcast is worth a listen.
