Here's Arthur Darvill Singing a 'Doctor Who' Version of 'Let it Go' - VIDEO

Just when we thought there couldn't be anymore versions of "Let it Go" from Frozen left in the world, former Doctor Who companion Arthur Darvill stepped in to let fans know that they should really let his character Rory go.

Part tongue in cheek parody about being called Rory and part promotion of his role in the West End musical Once, Darvill was a super good sport while performing the song for BBC radio.

Humorously referred to as "The Ballad of Arthur Darvill," lyrics include hilarious lines like:

"Let it go / Let it go / I'm not in Doctor Who anymore" and seeks to remind people that he's a real actor and not just a guy dressed like a Roman soldier who rides around in a T.A.R.D.I.S.
