Just a note re 'voice'.

Amos cleverly put the narrative in the first person - a great advantage when trying to fit a complex story into a short-line, short-verse song like House Of The Rising Sun. Singing "I" saves syllables (beats) over singing "Albert Walter Lyle" or even "Sparky."

The downside of telling Sparky's tale in the first person is that it makes it harder to tout his virtues without sounding arrogant.   It works fine for telling his baseball exploits, but I'm not sure it will work for a verse about what a "softie" Sparky is, how much he does for kids, or even what a wacky sense of humor he has.   Not saying it can't be done, but I think that's a challenge.
