In the history of rock music, no band has ever matched the Beatles’ success and influence. Paul McCartney co-wrote most of their songs, sang, and played bass guitar. He has been a vegetarian since 1975, and has long been among the most prominent celebrities to demonstrate massive commitment to animal protection. He initially went vegetarian with his first wife Linda McCartney, with whom he began his animal advocacy.
McCartney has appeared in numerous PETA campaigns, and has narrated animal rights videos including PETA’s factory farm expose Glass Walls. He has also supported campaigns started by the Humane Society of the United States (HSUS) and the World Society for the Protection of Animals.
In 2009, McCartney and his daughters Stella and Mary launched their own Meat-Free Monday campaign. On every McCartney concert tour, vegetarianism is extensively promoted at each of his events, and he routinely makes efforts to discourage the serving of meat during his tours.
