I only just discovered the term trock two weeks ago. A friend and I were comparing different Doctor Who inspired songs that we enjoy when she used the term "TROCK". It stands for Time Lord Rock, similar to the Wizard Rock which are songs and parodies inspired by Harry Potter.
I have waste hours on YouTube watching parody and original song videos. There are so many great song out there that every Thursday of the Whovian Countdown I will be sharing a different song. Today's Trock is a parody of "Hey Micky" redone by Leg Nose Robinson as "Hey Missy"
