"The Twelve Days of Christmas" is probably the most tedious Christmas song ever inflicted upon the English language. It's not the worst, but it still gets pretty old, fast. That's why it's so ripe for parody, with Bob and Doug McKenzie, Bob Rivers and a host of other folks doing funny riffs on it. To arrange the song in a way that's new and distinctive, and not a parody, however, takes a type of inspiration that's on an entirely different level. That's what we get with Straight No Chaser. Not only is their interpretation acapella, it's also a mashup of many familiar holiday songs (as well as one very non-holiday song) in an inventive and entertaining way.
