Rock god Dave Grohl has revealed he was "hammered" during the Foo Fighters' headline set at Glastonbury in June.

The band scored rave reviews for their set at the massive festival, which British press described as "charismatic" and "hugely impressive".

But Grohl says he was so nervous about the gig, he got plastered before going onstage.

The Foo Fighters frontman made the admission on the Apple Beats 1 Radio show It's Electric, hosted by Metallica drummer Lars Ulrich.
