According to the band’s press, Mumford & Sons randomly selected 150 fans from their mailing list and invited them down to London to feature in their video for ‘Guiding Light’. The band met all the fans at Flat Iron Square before teaching them the lyrics to the new song.

The band performed and filmed the video with fans in front of Tate Modern on the Southbank. Once the video was recorded, they performed an impromptu set in front of fans and passers by who had gathered to see the event.

The band performed stripped-back versions of ‘The Cave’, ‘Guiding Light’, ‘I Will Wait’, ‘Cold Arms’ and ‘Little Lion Man’. You can watch footage of the event here:

The band described ‘Guiding Light’, the first single from their new album, as “a dizzying folk-rock song that builds, builds, explodes and then explodes again,” the single premiered yesterday (September 21) on Radio 1’s ‘Hottest Record’.

Speaking to DJ Annie Mac about the new single, Marcus Mumford said: “It was a bit of a beast to try and get on record. It was hard work. We kind of tried it in loads of different ways…this one took a while. We wrote it like a year ago, but it’s taken a while to just get it to that point and now we’re happy with it.”

The band also revealed that they were still in the studio recording ‘Delta’ but expect to be finished this weekend.

Speaking about ‘Delta’ to Annie Mac, Winston Marshall added: “I think at the beginning [of recording the album] we kind of fell back in love with the old instruments we didn’t play on ‘Wilder Mind’ like the acoustic stuff and the more folky instruments but [we were] conscious [about] how we can make these instruments sound not like these instruments which opened up a whole new world for us…”

The band are also due to announce details of a world tour on October 4. ‘Delta’ will be released on November 16.
