Adele on why she said yes to Glastonbury

Adele tells BBC Radio 2's Jo Whiley she decided to headline Glastonbury after seeing Kanye West perform last year.

"I was so frightened watching his set, but said "yeah, I'll do it'," adding she wanted it to be part of her son's childhood. "I grew up at festivals and Glastonbury's a massive part of my life."
