This is medley of Doctor Who theme songs by the band The Aviators. They normally do music based around My Little Pony, but sometimes branch off into other areas, such as this instance. The Aviators is worth listening to, even if you are not a Brony.
I will post the other two songs from the EP soon.
This group need more views pass it on.
Such an EPIC version of I Am The Doctor. Really great work.
