METAL MAN. English, Waltz. D Major. Standard tuning (fiddle). AABB. The waltz was composed by English musician Robin Dransfield. It was named after a lighthouse in Ireland, erroneously, it seems, said to have been in County Cork. There are Metal Man lighthouses in County Sligo  and County Waterford, however, erected in 1821 and 1823 respectively, each supporting a statue cast from the same mold.
The County Waterford structure is actually a group of three round unpainted stone towers, about 30 feet tall, one of them topped by a cast iron sculpture of a sailor, his cap and coat painted dark blue and his trousers painted white, his arm outstretched to warn ships away from the rocks.
