The Time Lords?

So I found this song here, right here (please click here and press play on the thing that says "listen"!) on tumblr and I reblogged it. I since found out that it's a real song, called Doctorin' The TARDIS, by The Time Lords.

Except it's not.

Because HERE is the original (below) and the song which plays from the link above is NOT the same. Notice the different introduction? Notice the different guitar-y bit? Notice the verses with lyrics? Those are not in the original, it is not the same.

Now, I'm not saying anything bad about either song. I just have a question I want to ask.

And my question is this: where on Earth did the one in the top link come from? I looked up covers of the original song and none of them match this one. So who made it and where did it come from??

And more importantly: WHERE CAN I DOWNLOAD IT???

In the meantime, if you don't know the answer to these questions, which you probably don't, just listen and bask in the awesomeness of a song about Dr Who. :)
