The clip comes from the closing section of Frog Legs Rag, a ragtime piece written by American composer James Scott and published in 1906. Ragtime piano was a staple of early twentieth-century entertainment, later becoming shorthand in film and television for old saloons, silent comedies and the Wild West. Short excerpts like this one circulated on soundboards because the tune is instantly recognisable as vintage without needing any dialogue. It remains popular with editors who want a quick, comic signal that a scene is set in another era.
