"That the stones of the street may turn up the pig's feet If ever I cease to the love. That the tay may come down to three ha'pence a pound If ever I cease to the love"
The current description is all of the Tunney-StoneFiddle fragment.
The fragment is a parody of the "if ever I prove false" theme floating among songs such as "When First Into this Country" and "I Live Not Where I Love." It could be derived from "If Ever I Cease to Love" but the only line shared is "If ever I cease to [the] love." - BS
