Only one traditional text of this ballad survives (the 'two' texts in Child are the 'original' and the slightly altered Skene MS transcription of it), and no tune is known for it.

A few people have recorded arrangements, with texts altered to suit their tastes and set to tunes of their own making or borrowed from elsewhere. James used an unrelated tune from Playford that took his fancy; rather good, I thought. Mind you, it was me who explained to him what was happening in verse 4.

Note that 'Kempion' / 'Kemp Owyne' / 'Laidley Worm of Spindleston Heughs' (Child 34), although it involves a similar transformation, is a completely different story and shouldn't be confused with Child 36; or, for that matter, with 'Allison Gross' (Child 35) or 'The Lambton Worm'.
