Actor Dan Aykroyd made quite an entrance on The Tonight Show Starring Jimmy Fallon in America on Friday night (18Jul14) by performing one of his favourite James Brown tunes with rock 'n' roll veteran Bobby Rush. The Blues Brothers star portrays Brown's manager Ben Bart in new biopic Get On Up and decided to promote the film with a musical tribute to his late hero. Aykroyd and Rush performed Brown's I'll Go Crazy and the actor then explained to host Fallon that the number was special to him as he used it to persuade his late friend not to retire. Aykroyd explained he performed the track when Brown was part of the Kennedy Center Honors in 2003. The actor explained, "He was thinking about retiring and I sang it to kind of dissuade him from retiring - if you leave me, I'll go crazy... He was so much fun. He was a great guy, a wonderful man." Brown died on Christmas Day (25Dec), 2006.
