Music legend Stevie Wonder paid tribute to fellow soul star Bobby Womack as he closed the London Calling Festival on Sunday night.
The Superstition hitmaker headlined the final day of the event in the British capital, following on from Saturday night's bill-toppers Aerosmith.
Wonder thrilled fans with a hit-packed set, performing classics including Signed, Sealed, Delivered I'm Yours and Higher Ground
He also used his time on the stage to honour music veteran Womack following his death on Friday.
The star told the crowd the moment was extra poignant for him as he last saw Womack on a previous trip to the U.K., saying, "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 saw him last right here in England.
"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!"
Wonder and his band then burst into a cover of Womack's track If You Think You're Lonely Now, adding, "We picked out a song we thought was appropriate."
Other performers at the festival, partnered by Britain's Absolute Radio station, included Paloma Faith and Jack Johnson.
