Here's the scoop: "Lough Erne Shore" IS a tune from northern Ireland. But that is just the name of the tune. The lyrics that are sung to it are "Paddy's Green Shamrock Shore", which available in the DT. A great song. Similar thing happen with the Scottish tune "The Drunken Piper". That is the tune name, but the song sung to it is called "Far Am Bhi Mi Fhin".
