What is the last thing you would expect from the boys of One Direction? Well, there are loads of things you wouldn't expect from the boys, among them being a perfect performance of Philadelphia's unofficial theme song.
Niall, Louis, Liam, and Harry surprised their Philly crowd by performing the Fresh Prince of Bel Air theme song--rap and all. This isn't the first time they have performed the song, but it was no doubt a treat for the Philly crowd.
To be honest with you, if things don't work out in the pop business, perhaps there is scope for them to put out a rap record? Just thinking out loud.
