Sir Paul McCartney has recorded a song to accompany a TV advert for late wife Linda's vegetarian food range.
The commercial, which will be the first for the brand in fifteen years, will also feature an animated version of Linda, who died from cancer in 1998.
Elvis Costello is the second celebrity to join the advert's line-up. The singer, who has been a vegetarian since the 1980's, will narrate the advertisement.
Music veteran Elvis said: "Linda always talked well and made it seem that you wouldn't be joining a secret weird society by being vegetarian."
The song which accompanies the LoveLinda campaign ad is a re-recorded version of his song Heart Of The Country, which appeared on 1971 album Ram. It went on to be the B-side of his single The Back Seat Of My Car. The new version was done during a session with producer Mark Ronson.
