FILE - This Dec. 12, 2012 file image released by Starpix shows Paul McCartney at the 12-12-12 The Concert for Sandy Relief at Madison Square Garden in New York. McCartney is adding his voice to Tony Bennett's campaign against gun violence. The former Beatle recorded a voice message that's part of a text-to-call operation Wednesday, April 17, 2013, for Bennett's Voices Against Violence campaign. McCartney and others are encouraging Americans to send a text, which will lead to the singer's message and connect the caller to their local senate office after proving their zip code.
