Mumford & Sons surprised fans Tuesday night during their show at the Forum in Inglewood, California, when Blink-182 bassist Mark Hoppus and tour openers the Vaccines and Jack Garratt joined the band on stage to perform a cover of the Eurythmics’ 1983 hit “Sweet Dreams (Are Made Of This).”

In fan-shot footage from the show, we can see Mumfords and the Vaccines play electric guitars, Hoppus on bass, and Garratt on the digital drum pads.

Mumford & Sons debuted the cover during a BBC Radio 2 session, and they’ve dropped it into their set on the band’s latest tour, promoting their new album Wilder Mind.
