Very glad to see another verse or two to "Mo Mary."   

I heard this song performed by Peter and Isabel Gardner back in 1963 at Gerde's Folk City (Greenwich Village) and I bought their album "Folk Songs Far And Near" (Prestige ©1962).
In their version the shortage of verses wasn't a problem, as Isabel did wonderful flute interludes and they repeated the first verse.   But when I think of singing it, say, in a song circle, it comes out awfully short.

Beautiful song.
