The Salvation Army song Keep in step (S.A.S.B. 986) is given a tongue-in-cheek treatment, with the irony of a song that speaks of keeping in step at all times being used in a time signature that would be impossible to march to! This does make the music technically challenging and therefore careful preparation is needed to ensure everything remains within the correct bear, and that the rhythms sound convincing to the listener. There is also a touch of Broadway thrown in, with a recurring motif reminiscent of Gershwin's appropriately named Fascinating Rhythm.
