Kylie Minogue was one of the acts to take part in the hugely popular tribute for the pop-sensation ABBA. She took the stage with Super Trouper and later joined ABBA's Benny Andersson with When All Is Said And Done.
Minogue told this to be "a dream come true" to be on the same stage with Andersson, according to BBC.
Besides her Chaka Khan, Jason Donovan and Lulu performed the hits of the Swedish band, amongst others. Also appearing were the jazz musician Jamie Cullum, West End star Elaine Paige and Marti Pellow of Wet Wet Wet. Naturally, the London cast of Mamma Mia! were there too.
'Life can be pretty wonderful'
"I'm not a nostalgic person but tonight took me back," ABBA's other male counterpart Björn Ulvaeus told the crowd. "Life can be pretty wonderful. Thank you for giving us this unforgettable experience."
He also said he had never thought their victory at the 1974 edition of Europe's favourite TV-show would bring them to such success. The 36,000 people attending the event in London disagreed and proved it by singing along to every song, amazing Ulvaeus.
The event was hosted by DJ Chris Evans, lyricist Sir Tim Rice and the Swedish actor Stellan Skarsgård. It was broadcast live on BBC Radio 2.
ABBA won Europe's favourite TV-show back in 1974 with their legendary Waterloo. They became one of the most popular acts in the history of music, selling over 400 million albums to date.
Their winning song from 1974 was chosen by the fans and televoters all over Europe to be the best Eurovision Song Contest entry of all times, at the 50th anniversary show Congratulations in 2005. Also, a musical and a movie, based on the music of the band, have been extremely popular in the world.
