CHICAGO – Resilient youth was served at the 55th annual Grammy Awards Sunday, with relative newcomers such as Mumford & Sons, fun. and Gotye sweeping the major awards.

The Black Keys also enjoyed a banner night. The Nashville-via-Ohio rock duo won three Grammys, with guitarist Dan Auerbach picking up an additional award for producer of the year. Mumford & Sons won the biggest award of all, album of the year, for “Babel.”

But fun. didn’t go away empty-handed, nailing two major honors: best new artist and song of the year for “We Are Young.” In accepting the awards, the band reflected on its long climb to recognition over more than a decade. “But we’re old,” they cracked.
