 Material from "Born to Run" grew in importance as the tour went on, but even the newest material could be quickly recast.Most notably, "Thunder Road" was changed from the spirited, sweeping album version into a surprisingly quiet and pleading show opener, featuring Springsteen singing while standing still at the microphone stand, guitar slung behind him, with only Roy Bittan's piano and Danny Federici's electronic glockenspiel accompanying him.
