WTF? Jim Davidson sings 'Hello' John Malkovich

This scene's from Colour Me Kubrick, in which Malkovich plays a man who pretended to be Stanley Kubrick in the late 90s. Quite why Jim Davidson is singing Lionel Richie's Hello to the character is beyond my kenny, but this clip buggers belief in every possible way [via @james_blue_cat]. Prepare to be boggled...
