British singer Robbie Williams shocked audience members at the U.K.'s Sony Radio Academy Awards on Monday (13May13) by joking about the BBC's ongoing child sex scandal. The Angels hitmaker took to the stage at London's Grosvenor House, and during his performance he referenced Operation Yewtree, a police probe launched following claims late TV star Jimmy Savile abused hundreds of youngsters throughout his long-running entertainment career. The star said, "I looked around the tables and mine was the only name I recognised... actually, looking from up here it looks like the stars of Operation Yewtree 2014." His comment drew a collective gasp from the stunned audience, prompting the singer to ask, "Too soon?" Williams also launched into an expletive-filled rant aimed at Radio 1 presenter Nick Grimshaw after bosses at the BBC-run programme decided against playing the singer's 2012 hit Candy as the 39-year-old didn't reflect their target audience's music choice. During the ceremony, former Catatonia singer Cerys Matthews picked up the Music Radio Broadcaster of the Year for her show Cerys On 6 (BBC 6 Music) while the Best Music Feature or Documentary was won by The Story of Ed Sheeran (BBC Radio 1). TV and radio personality Dermot O'Leary was awarded the Best Music Programme prize for his self-titled BBC Radio 2 show and veteran presenter John Humphrys collected the Radio Journalism award.
