abc2svg at http://moinejf.free.fr/js/edit-1.xhtml will take the lyrics for Stan's Marianina abc as one w: line at the bottom:

w:O'er the o-cean flies a mer-ry fay Soft her wings are as a cloud of day, As she pass-es all the blue waves say: "Ma-ria-ni-na, do not roam, Whi-ther, whi-ther is your home, Come and turn us in-to foam, Ma-ria- ni-na, Ma-ria-ni-na, Come, O come and turn us in-to foam!"

I can't see atm how to split that up.

The latest version of abcm2ps I found on github will not take this.
