The current Allman Brothers line-up features two incredible players: Warren Haynes and Derek Trucks. During the band's set at this year's festival, Clapton joined the band. They performed Why Has Love Got To Be So Sad.
The song is a slightly different version of Why Does Love Got To Be So Sad from Clapton's Derek And The Dominos album, Layla And Other Assorted Love Songs. That album featured original Allman brother, the late Duane Allman.
