Mercury Prize winners Elbow have picked up two gongs at the Ivor Novello Awards. The band beat Nick Hemming, a warehouse worker without a record deal, and the Last Shadow Puppets to win best song musically and lyrically for One Day Like This. The band, who won last year's Mercury Prize after years of slogging, also picked up best contemporary song for Grounds For Divorce. Elbow's frontman Guy Garvey said: "If nothing else ever happens to me in my whole life, these four boys have made the whole thing worth every single second." The special international award went to Motown legend Smokey Robinson, while the Ting Tings' We Started Nothing picked up the best album award. Duffy, who was up for three awards, received the Performing Rights Society's award for music's most-performed work for her anthem Mercy. Coldplay, who also received three nominations, won best-selling British song for Viva La Vida.
