Lennon and McCartney's Studio Reunion

On March 28, 1974, John Lennon was in a Burbank studio producing Harry Nilsson's "Pussy Cats" album when Paul McCartney dropped in. The room froze and remained silent until John said, "Valiant Paul McCartney, I presume?" Paul responded: "Sir Jasper Lennon, I presume?" The tension broken, a jam session [Part 1] [Part 2] [Part 3] [Part 4] ensued featuring Lennon on guitar and vocals, McCartney on drums and vocals, Stevie Wonder on electric piano and vocals, Harry Nilsson on vocals, Jesse Ed Davis on guitar and Bobby Keys on saxophone. A bootleg of the session has circulated under the title "A Toot and a Snore in '74".
