Elvis Costello

Vegetarian

A vegetarian since the early 1980s, Costello says he was moved to reject meat after seeing the documentary The Animals Film (1982), which also helped inspire his song "Pills and Soap" from 1983's Punch the Clock. In January 2013, Costello teamed up with Paul McCartney to create an ad campaign backing vegetarian foods produced by the Linda McCartney Foods brand.
