Ronson pays tribute to Amy

GUT-WRENCHING MOMENT: Mark Ronson, in his first performance since the death of his friend and production client Amy Winehouse, paid tribute to her during a concert in London Wednesday night, the day after attending Winehouse’s funeral. Joined by former Zutons leader Dave McCabe and members of Winehouse's stage band, Ronson urged the crowd to "sing on top of your lungs" and then broke into "Valerie," the Zutons original that Winehouse brilliantly covered on Ronson’s 2007 album Version. He also told the crowd that the British singer was his "sister" and "musical soulmate." The crowd responded by shouting "We love you, Amy" before the song began. Here it is. (8/1a)
