It's not clear how many audience members realized that Wednesday night at Nashville's Sommet Center probably was their last Bruce Springsteen and the E Street Band concert. After almost two straight years of touring, Springsteen and E Street are going on hiatus after tonight's show in Buffalo. With most of the band members in their 60s, saxophonist Clarence "Big Man" Clemons's health issues and recent remarks from band members, the odds are good that Nashville saw one of rock's greatest live acts' third-to-last show.
