This song has an old-time feel, with a ragtime sound and lyrics that could easily have come from the 1930s.

The song was written by Freddie Mercury under his vaudevillian/musichall influence.
The song is probably best remembered for its “jazz band” bridge section performed vocally by Mercury and Roger Taylor in the middle part of the song.
The song’s “musical” bridge section was performed entirely by Mercury and Taylor using their voices alone, with Taylor at one point hitting the highest note on the whole album – a C6.
Mercury imitates woodwind instruments including a clarinet. Taylor voices mainly brass instruments such as tubas and trumpets, and even a kazoo. The tap dance segment is also “performed” by Mercury and Taylor on the mixing desk with thimbles on their fingers. Mercury plays both grand piano and jangle honky-tonk.
This is one of the few Queen songs without Brian May participating at all.
