The Guy From The Dropkick Murphys Would Like You To Know He Didn’t Really Say Jonathan Papelbon Couldn’t Use His Entrance Music 

Yesterday, ESPN Music(?!) reported that Ken Casey, vocalist for the Dropkick Murphys, did not want Jonathan Papelbon using his old entrance song. That song, "I'm Shipping Up To Boston," is reserved for the Red Sox closer, Casey supposedly said, and now that Papelbon is in Philadelphia, he's no longer welcome to it.
"They fucked me," Casey says via email. (You'll be shocked to know that his online handle contains both a Pogues reference and Larry Bird's number.) Casey insists he was joking, but the ESPN story played his comments as if they were legit. He doesn't blame interviewer Mike Trask...

Bullshit! I call Bullshit! The Dropkick Murhpy's are just backing out now that this story blew up. Stand by your convictions, man. Don't let Paplebon's scary stare intimidate you. The biggest key to being in a relationship is not change who you are or your ideals. If the Dropkick Murphy's truely consider Paplebon their friend the way they have hinted than this should be a moot point. Maybe this speaks more to the character of Jonathan Paplebon. Pap's may just be the type of guy who can't let things go, some may even go as far as to say he could be a hoarder. Holding on to a walk out song that has absolutely nothing to do with his new city. It's like the guy who goes to college and still wears his high school varsity jacket. Give it up Johnny. Create a new identity for yourself. And to the Dropkick Murphy's - stick to what you believe in and if someone in your life doesn't agree with that than they don't deserve you. Especially a pitcher who stares into the viewers eyes like a sexual predator doing research. Don't go changing Ken Casey. You've never let me down before.
