There are Irish songs titled Foggy Dew that pre-date the Easter Rising. There is a thread discussion on that topic if you search the forum.

Funny that last week in a performance of a radio show, one of the songs I sang was The Foggy Dew, the 1913 recorded version by John McCormack with the love song lyrics written by Milligan and the same tune as the rebel Foggy Dew ( discussion is in that other thread). A local rock band was also on the show, and when I went back to the green room, the lead in the rock band asked me if I knew The Galway Shawl. I said, yes, that's a great one to sing to other Irish musicians because it lists the tune titles. He said he had learned the Galway Shawl, but until that night when he heard me sing, he had never heard The Foggy Dew. So, then I wondered at the time myself, which Foggy Dew was meant in the song, could it even be this one, with the other tune?The Foggy Dew (A wan cloud was drawn...)

I am interested in knowing more about the history of the Galway Shawl, too.
