Watch Anthony Kiedis jam to The Beatles on bass during Red Hot Chili Peppers festival set

Band covered 'Hey Bulldog' at Pinkpop Festival in the Netherlands

Red Hot Chili Peppers performed an impromptu cover of The Beatles during their set at Pinkpop Festival in the Netherlands over the weekend.

During the band’s headline set, singer Anthony Kiedis picked up the bass guitar and began to string slap to ‘Hey Bulldog’ from ‘Yellow Submarine’. Watch footage below.

“That’s our new hit single,” Flea joked after the performance. “It’s big in Albania right now,” Kiedis added.

Red Hot Chili Peppers’ new album ‘The Getaway’, their first record since 2011’s ‘I’m With You’, will be released this week (June 17). It was produced by Danger Mouse and mixed by Radiohead‘s Nigel Godrich.

Meanwhile, bassist Flea has bemoaned the state of modern rock music, saying that the genre is dead.

Flea previously said that the band were “heading into a new era” as they finished work on the LP.

“We’re near the end of it,” Flea told Q. “Danger Mouse is producing this time, instead of Rick Rubin. Were heading into a new era and we’re really excited.”

Asked how the album was sounding, he added: “It’s new and different but without sacrificing the good bits of us. There are some songs we already had, and some new ones too. I can’t wait to play it live.”
