If only it were acceptable to begin reviews with the brain exploding emoji. Four virtual ABBA members, or ABBAtars, performed the premiere of their Voyage concert experience in a specially built arena in east London, and looked so convincing that I was left with no idea what was real and what was not. This bears overstating: I literally could not believe my eyes.
Was that really the King and Queen of Sweden sitting behind me? Could that truly be Keira Knightley, Jarvis Cocker and Sadiq Khan elsewhere in the audience? How can I not have bumped my head and woken up in 1979, when every hair on Seventies Benny Andersson’s arm is clearly visible, every flap of Seventies Agnetha Fältskog’s sparkling flares?
