Mumford And Sons feel like a "big boy band" following their Grammy win.
The British quartet scooped Album Of The Year, arguably the top award at the bash, for Babel.
The Daily Star quoted Ben Lovett, 26, as saying: "America has been so good to us.
"We've toured hard and we're excited about taking on the responsibility of being a big-boy band and stepping into the shoes of the big guys."
Marcus Mumford, 26, said the band thought that they would walk away empty-handed.
"One after another it was like: 'And the winner is Black Keys, the Black Keys, the Black Keys'.
"And so I think we just sort of resigned ourselves, like last year was Adele's year, it was the Black Keys' year and good on 'em, they're f*****g awesome.
"We honestly were just happy to be nominated. We really didn't care about winning."
