McCartney 'revisits' Beatles and Linda in song

Paul McCartney said today his concerts are a way of making contact with other Beatles members and his late wife Linda.

The singer was at a bar in London to launch his new CD and DVD set, titled 'Good Evening New York City', recorded during his three-night stint in New York’s Citi Field, formerly the site of the Shea Stadium which was the location for a famed appearance by the Beatles in the mid-1960s.
