Stevie Wonder paid tribute to the late Bobby Womack as he closed the Calling Festival in London on Sunday night.

The soul legend sent his ''condolences'' to Bobby's grieving family following his passing at the age of 70 and then covered his track 'If You Think You're Lonely Now' at the music event held on Clapham Common.

Speaking to the crowd, Stevie said: ''It's always a painful thing when we lose someone in this industry, but each time we lose someone, we can say we are left with their musical history ... I want to give my condolences to his family and hope that he is in the best place spiritually. Please give a hand to Bobby Womack.

''We picked out a song we thought was appropriate.''

The 64-year-old star performed a hit-filled set with highlights including 'Signed, Sealed, Delivered I'm Yours', 'Sir Duke', 'Master Blaster' and 'Sunshine of My Life'.
