Influential British 1960s band Cream reunited for a concert on Monday - 36 years after the group split.
Many fans travelled from the USA to witness the reunion
Guitarist Eric Clapton joined drummer Ginger Baker and bass player Jack Bruce for a series of performances at London's Royal Albert Hall.
The band last played together in 1993 when they were inducted into the US Rock and Roll Hall of Fame.
All four performances sold in less than two hours, with tickets changing hands for more than £500 on eBay.
Agencies had been offering tickets for the concerts for up to £1,700, and standing tickets at the top of hall were advertised for £350.
Many fans had flown over from the USA to witness the reunion, which Clapton, 60, is said to have agreed to because of the failing health of the other former members of the band.
Bass player Bruce, 61, has had a liver transplant, and drummer Baker, 65, is said to suffer from arthritis.
Cream last played at the Royal Albert Hall in 1968.
Although the band were only together for less than three years, they recorded three albums which sold more than 35 million copies.
Singles included Crossroads and Born Under a Bad Sign, I Feel Free and Strange Brew.
On Monday the band received a standing ovation after coming on stage unannounced and launching into I'm So Glad. After three songs, Clapton told the crowd: "Thanks for waiting all those years!"
He added: "We'll probably play everything we know - we'll play as long as we can."
Their set included all their most famous songs, including Crossroads, Spoonful and White Room. The encore was Sunshine of Your Love - their biggest hit single.

Before joining Cream, Clapton had previously been with the Yardbirds and John Mayall's Bluesbreakers.
Cream formed in 1966 but split acrimoniously in 1969.
Clapton, who recently celebrated his 60th birthday, went on to form Blind Faith and Derek and the Dominoes - with whom he recorded Layla - before carving out a successful solo career.
Jack Bruce and Ginger Baker both went on to play with numerous other bands, as well as recording with each other.
