The Vaccines cover Taylor Swift's new single - listen
The band covered the US star's 'We Are Never Ever Getting Back Together' during their set in Radio 1's Live Lounge.
The Vaccines were at Maida Vale in support of their second studio album Come Of Age, which was released on Monday (September 3).
The group recently told Digital Spy that today's kids are "being sold such bulls**t" when it comes to music.
"They have no interest in guitars whatsoever. A lot of the stuff that's popular is complete misogynistic s**t," Freddie Cowan added.
"I mean, Chris Brown shouldn't even be allowed on the radio. I think a lot of people responded to the honesty of our last record and hopefully those people are still with us."
The Vaccines have announced plans to tour their new album across the UK in November.
