Ending a month long European tour in London's Hard Rock Calling in Hyde Park, Neil Young encored with 'A Day in a Life'. After performing the first couple of verses alone, Paul McCartney jumped on stage to help sign the song her co-wrote with John Lennon.
After about a minute and a half of intense distortion and nearly ripping apart Old Black, his '53 Les Paul, McCartney returned to the stage to help end the madness.
