Next month, The Boss and The Piano Man launch a joint concert to benefit Barack Obama. Tickets start at $500 and climb to $10,000. Obama says he will attend the musical fundraiser at Hammerstein Ballroom on October 16, the day after his final debate with John McCain at Hofstra University in Hempstead, N.Y. "While John McCain is working to bring Republicans and Democrats together, Barack Obama was working to bring rock stars together," RNC spokesman Alex Conant said. "A good duet is no substitute for a good job."
