Since I was little I was told I had an great-great uncle who was a composer. I was also told he wrote the Marine Corp Hymn and Old McDonald. His name was L. Z. Phillips. I never saw the score from Old McDonald, but my mother said she saw it 30+ years ago when she married my father. My grandmother supposedly had it until her death, but I never found it. I have one Aunt who said she would look for it. I don't know if it is a wild goose chase or this really exists. There isn't much information on L.Z. Has anyone crossed over it in there searches?
