Sir Paul shows heart

Sir Paul McCartney made a heartwarming call to cheer up an MTA official just before she died of cancer — an act, Mayor Bloomberg said, that showed Paul’s “a super-nice guy.”

The mayor disclosed the tender gesture on his weekly WOR radio show yesterday, when a caller asked if the mayor could honor McCartney either as an “honorary citizen” or with the keys to the city.

The suggestion was so out of left field that host John Gambling wondered jokingly if the caller was the famed singer’s manager.

But the unexpected question offered Bloomberg a chance to disclose an act of kindness by McCartney toward Susan Kupferman, a senior official at the MTA who had previously worked as an executive at City Hall.

Kupferman was a colleague of ex-MTA board member Nancy Shevell, Paul’s wife. “I wasn’t on the call, but Sir Paul called,” recalled Bloomberg.
