By the end of the 18th century a new room in the pub was established: the saloon.[citation needed] Beer establishments had always provided entertainment of some sort—singing, gaming or sport.[citation needed] Balls Pond Road in Islington was named after an establishment run by a Mr Ball that had a duck pond at the rear, where drinkers could, for a fee, go out and take a potshot at the ducks. More common, however, was a card room or a billiard room.[citation needed] The saloon was a room where for an admission fee or a higher price of drinks, singing, dancing, drama or comedy was performed and drinks would be served at the table.[citation needed] From this came the popular music hall form of entertainment—a show consisting of a variety of acts.[citation needed] A most famous London saloon was the Grecian Saloon in The Eagle, City Road, which is still famous because of a nursery rhyme: "Up and down the City Road / In and out The Eagle / That's the way the money goes / Pop goes the <answer>weasel</answer>." This meant that the customer had spent all his money at The Eagle, and needed to pawn his "<answer>weasel</answer>" to get some more. The meaning of the "<answer>weasel</answer>" is unclear but the two most likely definitions are: a flat iron used for finishing clothing; or rhyming slang for a coat (<answer>weasel</answer> and stoat).
