Carnaby Street shoppers, loiterers or those that just happen to be walking down Carnaby Street at 6pm will be in for a pleasant, or not so pleasant, surprise tonight. It will all depend on their preference for 'Beatlemania'. According to this report a ginormous piece of music memorabilia in the shape of a 11 x 8 foot replica copy of the Fab Four's written contract will be erected at 6pm for all to sign and worship to the tune of John Lennon's Imagine. The Imagine Corporation are even giving away the real thing in a competition. I'd imagine this to be something akin to the current phone advert where everyone sings Hey Jude in Trafalgar Square for no apparent reason. A pen and the words to the song will no doubt see you through this historic evening!
