Bob Seger and his Silver Bullet Band rolled through New York’s Madison Square Garden last night. Early in the night Seger invited out his old friend and fellow rocker Bruce Springsteen to sing backup and play guitar on “Old Time Rock and Roll.” Seger described the sit in as a “Christmas treat.” Seger has also rescheduled his stop at Greenville, SC’s BI-LO Center for January 14. Springsteen will tour extensively with the E-Street Band in 2012.
