Mumford & Sons frontman Marcus Mumford has entertained fans with an intimate performance ahead of the band's concert at Glasgow's Hydro.

Fans waited over an hour to see him perform at Assai Records in Edinburgh on Tuesday afternoon.

The singer, who studied in the city, treated them to hits new and old before signing copies of the band's latest album.

Getting up onstage, Marcus quipped: "The other boys are still in bed!"

"Singing at this time isn't very rockstar, is it?" he added.
