My grandfather was from Sligo and used to sing the 'Isle of Innisfree' all the time. I remember it with a lot more verses, though. I finally went over to Ireland and took a ferry across Lough Gill to see it. I was surprised how small it was. When the captain said, "To our left is the Isle of Innisfree.." I said, "That's it? The song is longer than the island!"
