PHILADELPHIA -- Bruce Springsteen will perform an acoustic set at a rally in Philadelphia to help the campaign of Democratic presidential candidate Barack Obama register voters and recruit volunteers.

The program begins at 3:30 p.m. Saturday on the Benjamin Franklin Parkway. Preferred tickets will be distributed to those who sign up to volunteer. Pennsylvania's voter registration deadline is Monday.

Springsteen has endorsed Obama for president. He and fellow performer Billy Joel are teaming up in their first joint concert to benefit Obama next month in New York City after the final presidential debate between Obama and Republican nominee John McCain. Obama plans to attend that Oct. 16 concert.
