I’ve heard it said by Hollywood actors that people commonly think that if you’re a celebrity, you’ve met and hung out with all the other celebrities. They laugh about this because it’s simply not the case.

What about rock stars?

I’m sure the same is true, but with all the special surprise guests that pounce onstage and impromptu jam sessions at places like just the Stone Pony in Asbury Park alone, it seems as though they all know each other.

Bruce Springsteen, an icon in his own right, shared the stage with another living legend on Saturday night. The Boss performed two shows, on Wednesday and Saturday, at Anfield Stadium in Liverpool.

Now, for all his travels and all the nations, stadiums, arenas, clubs, and bars Springsteen has performed in, a fun fact is that he had never played Liverpool, England, before. You can already guess just by location who the special surprise guest was.
