The Daily News reports back that the two were "singing together for the first time ... to the delight of 2,500 people at the fund-raiser." The Boss told the audience to "Palin-ize" their expectations for the night, since the two had only rehearsed a little. Michelle Obama looked on from a balcony, as everyone was urged to "rise up and take back this country." The good seats cost $10K, and the likes of Anna Wintour and Harvey Weinstein were on hand, while Marc Jacobs-designed Obama tees were being peddled at the merch table. Joel invited his daughter Alexa Ray onstage and thanked "Sen. Obama for finally getting my kid into politics." Obama himself appeared on stage around 11:30 p.m., and warned the audience: "Don't underestimate the capacity of Democrats to snatch defeat from the jaws of victory. Don't underestimate our ability to screw it up. I want everybody running scared."
