Eddie Vedder performed one of his most expensive gigs to date, with tickets going for $20,000 per-person as he opened up for President Barrack Obama at a private fundraising event for the President's re-election campaign.

Dressed in a suit and strumming a mandolin, this was by far one of Vedder's more unconventional performances as he serenaded the President and the 85 guests in attendance at the home of signer-songwriter Don Miggs and Lisa DeBartolo. DeBartolo is the daughter of Edward J DeBartolo Jr, the former owner of the San Francisco 49ers, and runs the family's charitable foundation that regularly runs fundraisers for the Democratic Party.

Vedder performed two Pearl Jam songs, 'Rise' and 'Without You,' before playing two covers, first James Taylor's 'Millworker and Neil Young's 'Rockin' in the Free World.' The rocker then went on to discuss one of Republican candidate Mitt Romney's comments on the '47 percent', referring to his own experiences in the past.

The singer explained that prior to Pearl Jam he was a part of this 47 percent and thanks to government support, managed to get a job as a security guard - eventually rising to the post of security supervisor at a petroleum company. He explained that it was this job that helped him to afford "guitars and microphones" and that Romney's dismissal of such a "ginormous amount of the population" was very upsetting.

Mr Obama then took to the stage and thanked Vedder for his comments and thanked him for sharing a story that so well captured "what this campaign is about and what this country is about."
