I'm looking for the melody - any format - for this folk song about Emilio Carranza, the son of Mexican president Carranza. He was a pilot who flew from Mexico to NY, but died on the return flight when his plane was hit by lightning. It was a popular ballad in the Southwest U.S. around the early 1900's, and I'm told my grandfather used to sing it, accompanied by his guitar and his brother on banjo. I have the lyrics, but would like to hear the melody.
