In a recent appearance on 'Late Night With Jimmy Fallon,' Nicolas Cage delved into other topics besides his career in film. Not only did the 'Leaving Las Vegas' star join Fallon in a duet of Squeeze's 'Tempted,' he also busted out his old impersonations from his days of hosting 'Saturday Night Live.' Cage treated viewers to his impersonation of Elvis Costello and sang '(What's So Funny 'Bout) Peace Love and Understanding.' Later that month, Elvis himself appeared on the talk show and was shown the clip of Cage's impression. The actor's rendition of the Costello classic was anything but good, but since Cage is a big fan and Costello is a good sport, the singer-songwriter comically responded, "He's a natural for the biopic."
