Sam Hinton would have been the first person to tell you he DID NOT speak Gaelic. Yes, he does sing a few verses of "Eagle's Whistle Lullaby" in this language. He told me that when he recorded his Lp of Irish folksongs in 1957, "The Real McCoy," "...we had an Irish student here at Scripps who taught me some of the pronunciations in Gaelic. His name was Colm oH'eocha. He became President of the Galway Campus of the National University of Ireland. He's now retired."
