Originally a hit song for pop artist Rhianna, Tom's arrangement is derived from the version performed by the award winning acapella group The Treblemakers in the critically acclaimed music comedy film Pitch Perfect. The movie follows all-girl acapella group The Bellas in their attempt to beat the reigning national acapella group The Treblemakers. You may not have seen the movie, but rest assured that many of your students have. Armed with this information and this great arrangement by Tom Wallace might be your chance to finally be relevant... Imagine that.
