Why does it have to be one or the other? The "and words or tint" works both as the completion of the sound and stone line and the beginning of a new sentence "And words and tint I did not stint". It's not possible to convey that on a written page, because you need to opt one way or the other with the punctuation. But you can sing it that way and it works.

I woul have no problem with people changing lyrics to suit the way they want to sing a song. It doesn't take away from the song/poem as written or other people's versions of the song.
