I think I may make the verse more general rather than more specific. If there's this much discussion about Orpheus here, it's going to be more noticable in the song. I'll get to that line, and people will think "Orpheus who?" I don't need a mythological figure - I need something that calls people as a metaphor, and I need it to mean something to the most people.

Maybe something like the following. I know it sounds a bit clumsy. (First person: "You're love's a distant campfire light." Second person: "Excuse me?!") I"m just trying to convey the image at this point.

Your love's a distant campfire light, a sweet, compelling flame
And the chorus 'round it, far away but strong
One stands apart, on hushed and shadowed path,
And yearns to join the vision or the song.

This also does something else I like - it ties the double metaphor of light and sound together. I wondered if the song was somewhat confusing because I'd had both of those things in there before. This would put them both in one place, but I don't know if the image is strong enough. In any case, I think I need to let the song mulch in my brain for a while.
