A recording of the Carter Family singing 'Jealous Hearted Me' can be found on The Carter Family 'On Border Radio 1939 Vol 1' Arhoolie CD 411. I don't know whether it's the full song, as I have never heard it elsewhere. The recording has 3 verses and chorus. It is on the same track, but discrete, following a rendition of 'Engine 143' by the then 10-year-old June.--Stewie.
