ABC's Maeva Bambuck reports from London: Thirty pianos have been placed in the streets and tube stations of the British capital this week, to encourage Londoners to take a musical break from their daily routine. At lunchtime this Wednesday, the instrument in Hammersmith failed to strike a major cord, with only a few brave people daring to approach it. The pianos have appeared in areas such as St Paul’s Cathedral, Liverpool Street, and the Millennium Bridge, locked to benches and lampposts and painted to match their location. An initiative by London’s eccentric mayor Boris Johnson to kick off summer on a high note, they are available for anyone to play and engage with. London has until July 13 to uncover its hidden talents. Let’s hope its infamous weather, and its yobs, don’t deface the pianos first.
