Yes, that is right, the former Beatle is a spokesperson for PETA (People for the Ethical Treatment of Animals). There are many reasons why celebrities would get with a involved a charity, foundation, or organization.
The most important reason is that celebrities can bring attention to a cause that may otherwise be ignored – ordinary people tend to notice when famous people do things, including an advertisement or a commercial for a specific charity. Charities will often ask a high-profile individual to attend a benefit or a function for these purposes.
The celebrity has his or her reasons also. Any PR rep would tell you that having your name attached to a charitable cause is good press and good exposure. Additionally, a lot of celebrities do not want to seem one-dimensional, and being part of a charity or foundation shows their multi-dimensionality. Finally, for some it is a personal issue: Sheryl Crow, a survivor of breast cancer, is one of the main proponents for the nonprofit Stand Up To Cancer.
