Here's my a cappella group's version of the mixed up 12 Days of Christmas, fashioned after Straight No Chaser's performance.
1) We sing this slower than Straight No Chaser does for a few reasons, but primarily so that we can remember what we're supposed to be singing after we've had a cocktail or two. Also because we want to be sure the audience can follow along after THEY have had a cocktail or two.
2) This is a live performance at a bar. The acoustics are pretty good considering, but keep in mind that no one has a mic, so the "balance" of our vocals and harmonies is only as good as where you (or a video camera) happens to be standing.
3) While we would love to transition into "Africa," doing so loses its effect when you don't have an amazing black guy who can bring it home with a tremendous falsetto. Thus, we went in another direction.
