Watch Amy Winehouse ‘punching’ a fan at Glastonbury

Was the singer defending herself during Pyramid Stage incident?

Footage of Amy Winehouse punching a fan during her Glastonbury performance last night (June 28) has appeared online.

The singer ended her show singing ‘Rehab’ from the photo pit when the scuffle broke out.

It was not clear at the time what caused it, but festival boss Michael Eavis later said the fan had grabbed Winehouse‘s breasts.
