WHOVIANS I NEED YOUR HELP

Around two or three years ago when I first started using Tumblr, I came across an audio post of the Doctor Who theme with lyrics.  It was just a couple guys singing and playing it on acoustic guitar and it was very cute and clever, and I HAVE NOT BEEN ABLE TO FIND IT AGAIN.

I remember clearly that it was an audio post, not an embedded video.  I’ve looked on YouTube, to no avail.

Does anyone remember this? Can you help me find it?
