McCartney on Vegetarianism, Glastonbury and Xmas Carols

Ten years ago Sir Paul McCartney set up Meat Free Monday - a campaign to encourage people not to eat meat on one day of the week. It is estimated that up to 5000 schools in the UK now have meat free Mondays.

In an exclusive interview for Radio 4's World at One, Sir Paul tells Sarah Montague how that campaign came about, young climate activists, and his unreleased record of Christmas carols, made just for his family.
He also shares his thoughts about appearing at the Glastonbury Festival in 2020.
