Ludwig Van Beethoven's magnificent 7th Symphony, would you believe, has an Irish connection.
I first heard the complete Symphony on a vinyl album decades ago. It was then the fourth movement caught my attention. It definitely sounded Irish!
Further research on the work described by Wagner as the "Apotheosis of the Dance", revealed the Fourth movement of the symphony was based on an Irish song, "Save Me from the Grave and Wise".
As movie star Michael Caine famously says, "Not many people know that".
