A solitary white piano at a John Lennon retrospective invites visitors to play the song “Imagine.” Curator Emma Lavigne said it was a deliberate effort to make people revisit the song that otherwise “you might hear in a supermarket, doing your shopping.” “The message is still there. This song is still relevant,” she said. “I wanted the exhibition to be as alive as possible, so we don’t say to ourselves that he (Lennon) is in a museum – because I think he would have hated that.” “John Lennon, Unfinished Music” is at the Cite de la Musique in Paris for the next eight months. The exhibition is on two floors: one for Lennon’s childhood and the Beatle years; the other, with white rooms, for the latter period when he was with Yoko Ono. Ono, Lennon’s widow, lent about 90 percent of the hundreds of exhibits that make up the show. The loans left Ono with “holes in her apartment,” Lavigne said. A 1966 pink, yellow and red portrait of Lennon by Andy Warhol, which Lavigne said usually hangs over the fireplace at Ono’s apartment in New York City, is exhibited above an upright Steinway that Lennon played when composing “Double Fantasy.” Other gems: Lennon’s black 1963 Fender Telecaster with a worn fingerboard and rusty pickups; collages he made for Ringo Starr and George Harrison; a 10-minute film of silent crowds in Central Park mourning Lennon’s death; and a copy of Lennon’s original “Imagine” – three verses written on New York Hilton letterhead. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
