I get asked this all the time. Why do you see Bruce multiple times on the same tour and as I've frequently done when I can afford it, multiple times within a few weeks span (I saw him 4 times the previous 3 weeks)? Here's why, you never know what The Boss will play. This from Backstreets regarding Night #2 in Chicago:
Clearly about to play "Girls in Their Summer Clothes," Springsteen called quite an audible to lead off the encore instead. The change of heart came from seeing some kids right up front in the pit: "There are a lot of young folks up here tonight," he said, switching guitars and calling out (an un-soundchecked) "Thunder Road" to the band. "Last time we played this was five years ago... but we played it for 35 years before that, so maybe it'll balance out." It did -- well-rested, with Bruce clearly wanting to play it rather than feeling obligated, it was the best "Thunder Road" in recent memory.
Add 6 songs not played the night before including Tunnel of Love and Spirits in The Night proves why you must see Bruce multiple times and even back to back nights when he is in town. As my Uncle Gary who has seen The Who, The Grateful Dead, The Stones, Hendrix, and other various classic rock bands has said after every Springsteen concert I've taken him to, "Bruce Springsteen is Still The Greatest Live Performer Ever"
