Sontaran (The Year Ahead?)
From Tardis Wiki, the free Doctor Who reference
In January 1991, a Sontaran attended a performance of the second Ultimate Tour along with a Dalek, Cyberman, Ogron and Zygon. After looking at those in attendance from behind the curtain, the Sixth Doctor thought to himself that the night's audience would be a difficult one to please. (NOTVALID: The Year Ahead?)
