I've got a June 1930 recording of 'Jesus is my air-o-plane', performed by Mother McCollum on JSP Records jsp7759d "the Guitar Evangelists". The lyrics are quite similar to those above. It sounds like two guitars or possibly one of them a twelve string guitar, with a slide style similar to Maybelle Carter. I don't know if Mother McCollum is playing one of the intruments or not. Thanks....BA
