Mumford & Sons were reduced to tears at the Grammy Awards on Sunday (10Feb13) when they came face-to-face with their musical heroes.

The British folk stars were on a high after winning two prizes, including Album Of The Year for Babel, but bassist Ted Dwane admits the night was also memorable because they got the chance to meet some of their idols.

He tells Rolling Stone, "It felt really weird. We'd been (to the Grammys) a few times. The physiological experience of sitting there and being shortlisted and calling out someone else's name was rehearsed. But this third time, we won. They called us up. And it was the big one, as well. Really crazy...

"I remember seeing the Black Keys at a venue twice the size of this dressing room. I was a die-hard fan. It's just so weird being in a category with them. Sitting next to them, these people I've had posters of. I was in tears."

Frontman Marcus Mumford adds of meeting Jack White, "He was so nice - I was so surprised," while banjo player Winston Marshall was thrilled to have a chat with Rage Against the MAChine's Tom Morello.

Marshall explains, "It meant a lot to me. I was a bit too young to see Rage before their hiatus, but I went to every single Audioslave (Morello's band) show in London. I went to three in a row once. I f**king loved that band. I loved Tom Morello. To have him liking our music - apparently he'd been to our gigs - for me was just f**king surreal. We talk to these people, and whether it's f**king Jack White or Elton John, they're just lovely people who love music as much as you do."
