Iconic Isle of Wight Festival duet between Amy Winehouse and The Rolling Stones almost never happened

The Isle of Wight Festival organiser John Giddings has revealed that the iconic festival moment when Amy Winehouse joined The Rolling Stones on stage to sing 'Ain't Too Proud To Beg' in 2007 almost never happened because the 'Back to Black' singer was too nervous to duet with Sir Mick Jagger.
