Metallica's Sunday night headlining slot on the Glastonbury schedule was met with contention when it was announced, but to their credit the LA metal-heads have taken all the criticism in stride.

After artists from Arctic Monkeys to Judas Priest questioned their involvement, band even made T-shirts featuring a number of the harsher quotes to sell as merch. 

And in response to festival fans' petition to have the band removed from the bill because of frontman James Hetfield’s involvement in a History Channel mini-series about bear hunting, the band opened their set with a nearly eight-minute short film mocking the controversy.

The clip — called "Glastallica" — was directed by English filmmaker Julien Temple and opens with scenes from "The Good, The Bad and The Ugly" before cutting to a collection of film footage (1973's "The Belstone Fox" among them) of fox hunts in the British countryside. "The River Kwai March" by Mitch Miller and Sweet’s "Fox on the Run" soundtrack the short, which takes a twist at the end when bears come out from the woods and start shooting the hunters. Those bears are revealed to be none other than Hetfield and his bandmates, joyously celebrating.
