Darren Criss's "Not Alone" studio single

I see BWW is plugging Criss's new single release of his signature tune from "A Very Potter Musical." I looked at the site, and it appears it's only available with the purchase of a T-shirt. Is there another way to get just the song?

I have wanted a real recording of that song for years (other than the demo version on his EP), as I've done it in small concerts and cabarets multiple times. However, I don't have much use for the t-shirt.

Just checked Tumblr- the song isn't even released to shirt owners until 12/23/15.

I tried to do a medley of that song with Howard Shore's "Waltz in A" that closes every episode of SNL, but the backing band got tangled up on the chord changes.
