Examples
Internal rhyme schemes were extremely common in popular song of the Swing Era. One familiar example is the bridge from "Don't Fence Me In," written by Cole Porter for the film "Hollywood Canteen" in 1944:
Just turn me loose let me straddle my old saddle,
Underneath the western skies,
On my cayuse let me wander over yonder,
'Til I see the mountains rise.
