Bruce Springsteen’s ‘Wrecking Ball’ world tour resumes tonight (May 25) in Frankfurt, Germany after a week-long break. The time off has given us a chance to catch up on listening to all the bootlegs we’ve downloaded (oops, did we say that out loud?), as well as notice how the setlists have varied from night-to-night.

While only a small percentage of the fanbase would object if he played virtually the same set every night (you know, the weird ones like us who keep spreadsheets of this stuff), Springsteen likes the idea of making every show unique for the fans. Just as importantly, it keeps the E Street Band sharp and on their toes.

To date, a total of 94 songs have been performed at 26 shows (including the warmups at the Apollo Theater and SXSW) and only two concerts have seen no debuts given. So we thought we’d take a look at the five most surprising rarities the tour has given us so far, beginning with 'Seaside Bar Song.'
