Mick Jagger took a turn fronting an all-star blues band at last night's celebration of the music at the White House, singing Otis Redding's "I Can't Turn You Loose" and paying tribute to the late guitarist Hubert Sumlin with a Howlin' Wolf song that featured Jeff Beck. In between, Jagger told the audience about loving the blues from an early age, when he often saw Sonny Boy Williamson perform in England. The harmonica player, he said, took note of the blues-loving young bands like the Rolling Stones: "Those English boys, they want to play the blues real bad," he said. "And they do – real bad."
