SP, the song is in fake Cajun/English dialect, "pidgin English". See above for explanation of file powder. The others are: Gumbois a stew made with okra and file powder, Ma cher a mio is Hank's bad French for "my sweetheart", Fill fruit jar is a refernce to home made corn liquor, "moon shine" served in canning jars. Son of a gun" is just an American Western/cowboy idiom, like Holy cow, Geeze Louise, etc. Do you have the rest of the verses in English so you can translate them, or should we post them? Do you know the tune? Good luck
