Bing Crosby
From Tardis Wiki, the free Doctor Who reference
Bing Crosby (2 May 1903-14 October 1977) was an American singer and actor.
At the time the First Doctor, Sara Kingdom and Steven Taylor crashed a film set, he was a clown working on a film for Ingmar Knopf. He was depressed because Charlie Chaplin had trademarked the good gags. (TV: "The Feast of Steven" episode of The Daleks' Master Plan)
Later, the Third Doctor was once serenaded by the Brigadier, a fan of Crosby's, who was badly attempting to recreate Crosby's signature tune, "White Christmas". (PROSE: Smash Hit)
