Singer Bruce Springsteen delighted fans with a jokey impersonation of U.S. President Barack Obama during a free concert in Virginia on Tuesday (23Oct12).

The Boss took to the stage for half an hour at the nTelos Wireless Pavilion in Charlottesville and even performed a humorous 'campaign' song at the event, which doubled as a re-election rally for the incumbent President.

Around 5,000 fans were treated to the song, which included the lyrics, "First debate really freaked me out/ then Romney got schooled twice by Obama/ Smilin' Joe Biden brought the drama/ Fox News must be smokin' marijuana," according to The Hollywood Reporter.

Springsteen has previously appeared at Obama rallies in Parma, Ohio and Ames, Iowa. The U.S. election will take place next month (Nov12).
