While performing live on a British television show one day in 2002, Robbie Williams forgot the lyrics to one of his own songs. He apologized to the audience and explained that he would have to start over -- because someone (a female someone) in the crowd had distracted him.
[Among the records that changed Williams' life? Dr Hook's Greatest Hits. "You can nick as many lyrics as you like," he once explained, "because no one will know."]
