From "Rock Notes," a short parody of news about rock celebs off of the 1980 comedy album, Monty Python's Contractual Obligation Album,:
Divorced after only eight minutes, popular television singing star, Charisma, changed her mind on the way out of the registry office, when she realized she had married one of The Donkeys by mistake. The evening before in LA's glittering nightspot, the Abattoir, she had proposed to drummer Reg Abbott of Blind Drunk, after a whirlwind romance and a knee trembler. But when the hangover lifted, it was Keith Sly of the Donkeys who was on her arm in the registry office. Keith, who was too ill to notice, remained unsteady during the short ceremony and when asked to exchange vows, began to recite names and addresses of people who also used the stuff. Charisma spotted the error as Keith was being carried into the wedding ambulance and became emotionally upset. However, the mistake was soon cleared up, and she stayed long enough to consummate their divorce.
They beat Britney Spears' 55 hour marriage to Jason Alexander by 29 years!
