Watch Paul McCartney Rap About Vegetarians

Sir Paul McCartney is not only one of the most famous musicians in the world, but he is also one of the most famous vegetarians in the world. In a new video, McCartney melds those two passions together into a jingle to promote Meat-Free Mondays.

The Meat-Free Monday movement stems from the idea that cutting out animal products from the human diet — even just getting meat consumption down to one day a week — can reduce greenhouse gas emissions. In this clip released ahead of the UN climate summit on Tuesday, McCartney calls on politicians and the public to commit to a weekly meat-free day to raise awareness of the environmental impacts of eating meat.

At the end of the call to action, McCartney starts rapping the web address for the organization. It’s hard to tell whether the former Beatle intended to burst into song, or whether he’s just so musically inclined that he couldn’t help it. One thing is for sure, though, you won’t forget that web address anytime soon.
