Fans of David Letterman's late night talk show will be getting several healthy doses of Foo Fighters this week - and the first installment was a cover of Black Sabbath's classic 'War Pigs'.
Dave Grohl and his band teamed up with American musician Zac Brown (who appears on the band's new album 'Sonic Highways') to perform Ozzy's famous tune.
Foo Fighters will be on set with David Letterman all this week in the lead-in to their 'Sonic Highways' documentary and album of the same name. The doc will debut on Friday after their residency is completed, while the album will be released in the first week of November - both of which we're hugely excited to experience.
