Glee creator Ryan Murphy opened the speculation floodgates this morning when he tweeted a photo of Lea Michele (Rachel) and Dean Geyer (Brody) with the caption “Creep drama.” Could it be that the two are filming a duet of Radiohead’s “Creep” for an upcoming episode? It seems pretty likely to us.

However, the original version of the song is a solo vocal, not a duet. And — as cult favorite Jonathan Coulton discovered when his unique arrangement of Sir Mix-a-lot’s “Baby Got Back” turned up on the show — Glee seems to have a habit of “borrowing” arrangements from YouTube when they need a version that strays from the original. (Like, for example, an acoustic folk version of a 90s one-hit-wonder rap song.)

We’re not trying to accuse Glee of cribbing another arrangement before it even goes down. Perhaps they really did create their own original duet arrangement for Rachel and Brody to sing. All we’re saying is that we wouldn’t be entirely surprised to hear another familiar YouTube rendition of a popular song if/when the show tackles this Radiohead classic.

So, if we were the types to gamble, we would put out money on this version:

The harmonies in this duet are so good they give us the shivers, and the power belt that female vocalist Caitlin Notey delivers about 2 minutes in is right in Lea Michele’s (Rachel) wheelhouse. We can already hear her and Dean Geyer (Brody) crooning this heartbreaking duet together.

We’ll be listening closely to see if the Glee version a) actually happens and b) sounds like this one. What do you think: Are we on to something here? Will Glee bite another YouTube sensation’s steez, or are they done trawling the internet for their song arrangements after Jonathan Coulton took them to task for nabbing his?
