OK, if you already have the first verse aligned, then you don't need Harmony!

Harmony has an option to take a text file, either supplied by the user, or extracted from the W: lyrics, and let you assign the words to individual notes, one at a time. You just indicate which note you want the next word to apply to.

It will also do the whole thing automatically, but you may have to adjust the result, using the shift words functions. These shift all remaining lyrics (i.e to the right of the current note) one space to the left or right. This is often quicker than assigning words one at a time.

So it is really assisted manual conversion.

Harmony can also actually display multiple aligned verses, but cannot yet create them itself - it has to be there in the input abc file.
