Why did Jennifer Hudson sing "Let's Stay Together" at the inaugural balls instead of Al Green? Because Green had another gig.
Hudson sang the song as President Barack Obama and first lady Michelle Obama danced Monday night.
Green's representative says he had been asked to sing but he had a scheduling conflict. Green says he'd be honored to sing for the president in the future.
