Bruce Springsteen used his latest fundraising bash for Democrat Barack Obama to poke fun at one of the presidential candidate's Republican rivals, Sarah Palin.
Springsteen dueted with fellow rocker Billy Joel for the first time ever at the bash, at New York's Hammerstein Ballroom on Thursday.
And the 'Born to Run' hitmaker jokingly compared the pair's inexperience to criticism of Alaska Governor and vice presidential candidate Palin.
He told the crowd: "Billy and I have rehearsed a little, but you have to consider this more like the vice presidential debate: you have to Palin-ise your expectations. We seem like we know a lot, but we don't really."
Springsteen and Joel were joined at the fundraiser by india.arie and John Legend.
