The Shake It Off hitmaker performed at Radio 1's Big Weekend event in Norwich, England ahead of the Foo Fighters' headline set, and during the show Grohl dedicated three songs to the singer because he was so amazed to land such a famous support act.

The rockers kicked off their first full show of a U.K. tour a day later (25May15), performing at the Stadium of Light in Sunderland, England, and Grohl called out Swift again by honouring her with a performance of the band's track Congregation, which was recorded in the singer's former home of Nashville, Tennessee.

Grohl also vowed to continue his Swift song campaign by name-checking her every time the band plays Congregation in future, telling the crowd, "I think I might dedicate this song to her every time we play it."
