Okay, I love photo bombing... if I ever appear in the background of one of your shots...I apologize, but I'm secretly stoked to be a part of your moment's documentation.
And these days bands are so manicured you rarely get awesome moments of randomness that become those iconic moments we all remember.
There are very few album covers as recognizable as The Beatles' Abbey Road. And pretty much everyone who visits the studio takes their own shot.
But did you ever notice the old dude in the background of the original? Best part of his story... the fact that he actually dislikes the band.
