Grammy success for Fun, Gotye and Mumford & Sons

The 55th Grammy Awards have taken place in Los Angeles, with Fun, Gotye and Mumford & Sons among the main winners.

Fun's anthem We Are Young, featuring Janelle Monae, was named song of the year, with the New York band going on to win the best new artist prize.

Gotye's international hit Somebody That I Used To Know received the record of the year, one of three prizes received by the Belgian-Australian artist.

Mumford & Sons took home the album of the year prize for Babel.

The English folk rockers received their honour from countrywoman Adele, who had earlier won best pop solo performance for her live version of Set Fire to the Rain.

Mumford & Sons had received six nominations ahead of the ceremony. In the event, though, their only other prize came for best long form music video.

Sting, Bruno Mars and Rihanna joined forces for a Bob Marley tribute that featured Rihanna and Marley's son Ziggy duetting on his father's 1980 classic Could You Be Loved.

Sir Elton returned later to perform in another all-star collaboration, paying tribute as he did so to the 26 people killed in the Sandy Hook Elementary School shootings last December.

The event was preceded by a pre-awards ceremony at a neighbouring venue at which the majority of this year's prizes were handed out.

Winners announced ahead of the main event included the late Indian sitar player Ravi Shankar, whose award for best world music album was collected by his daughter Anoushka.

The event saw a surprise appearance from Prince, who appeared sporting black sunglasses and a white cane to present the record of the year award.
