Paul McCartney has just issued an animated video for his 1993 animal rights protest song, "Looking For Changes" in support of PETA (People for The Ethical Treatment of Animals). The song, which ranks as McCartney's fiercest denouncement of vivisection and animal testing for medical and cosmetic research, was originally released on 1993's Off The Ground and performed nightly on that year's "New World Tour." McCartney has only played the song once in the ensuing years at a PETA benefit in 2015.

Paul McCartney explained why he decided to become vegetarian back in the early-1970's: "My original thing, which is still at the core of why I'm a vegetarian, was compassion. So, years ago, Linda and I were on a farm and we had sheep and they had lambs. And it's the most beautiful time of the lamb's life. They're, sort of, full of spirit and full of energy and we happened to be eating leg of lamb. I said, "Y'know, should we try and not do this?' So we did it and never looked back. But it basically was, sort of, out of compassion for these lambs who were just born, were in the first month of their lives, and were shortly to have it ended. 'Didn't seem right."
