Someone just found a way to make me find A Capella very compelling.
The Blanks are best known as “Ted’s Band” on the TV show Scrubs. They are in fact a real life a cappella group. The above adaptation of Hey Ya! (originally by Outkast) was partially used in an episode at one point. It reminds me of this Mat Weddle of Obadiah Parker cover.
Related is The Blanks doing a cover of Superman (the Scrubs theme song).
I might like musical parodies a bit.
