Rick Wakeman will be joined by Alice Cooper next year to perform his 1975 LP 'The Myths and Legends of King Arthur and the Knights of the Round Table'.
The third studio album from the keyboard player - based on the legend of England's medieval monarch King Arthur - will be recreated live and in full with the help of the 'Poison' rocker, when the pair headline the first ever Stone Free Festival at The O2 in London in June 2016.
And the 66-year-old musician is delighted he's getting the opportunity to perform the concept album again.
He said: "After the success of the 'Journey To The Centre Of The Earth' shows last year, I'm over the moon to have the opportunity to perform 'King Arthur' for the first time since 1975 with an orchestra and choir. It's going to be wonderful."
The iconic LP contained prog rock classics such as 'Arthur' and 'The Last Battle', which is over nine minutes long, and was written after Rick survived three heart attacks at the age of 25.
Alice, 67, is thrilled to be joining his old pal on stage.
The singer said: "Coming to the UK is always like coming home for us, fans in the UK are always high energy, always there. Headlining the very first Stone Free Festival at London's The O2 in June next year is an example of why we feel so welcome. It will be my only performance in the UK next year, so that makes it even more special. And as always with my show you can expect the unexpected!"
Day and Weekend and Rock Royalty tickets for Stone Free Festival will be on general sale at Stonefreefestival.com on November 20.
