Paul McCartney wants people to know he's keeping up the animal-rights work that he and his wife, Linda, began years ago.

The former Beatle said some people have wondered about his own commitment to the cause, since Linda took a more visible role that included promoting animal rights and marketing her own meat-free dishes. She died at 56 from breast cancer in April.McCartney told Animal Times - the magazine of the animal rights group People for the Ethical Treatment of Animals - he is committed to "keep this torch burning."
