Update: The group is called The Blanks, and they have a CD out. You can hear them on Acapodcast #9 singing a full length version of the Scrubs theme song “Superman”. It starts at about the 13 minute point on the 28 minute podcast. Here’s a realaudio stream of a complete cut from their album called “A Little Polish”.
Did you see this segment on the NBC show “Scrubs” a few weeks back? Hospital business manager Ted has an a cappella quartet, and they take on a classic. I could so see this as Makeshift schtick.
