So happens that ABC Family aired the original "Hairspray" film last night, complete with the "Madison Time" sequence that does not appear in the new movie. (A version is in the Broadway musical, with Corny calling the dance moves.)
Here's a clip from the 1988 movie, cut off during Eddie Morrison's call of the Wilt Chamberlain basketball step. That's a younger and portlier Ricki Lake playing Tracy. If you can read choreography notation, here's how you can do The Madison at home, complete with all the steps for all the custom moves, from the Cleveland Box to the big strong Jackie Gleason.
It's interesting to note that The Madison did not originate in Baltimore, but rather in Columbus, Ohio.
