Blue Smoke was actually written by Merle Travis's brother John Travis. Mr. John played it out of Am and did it slower. He wrote several of Merle's songs. There used to be alot of tapes of Mose Rager floating around here locally. I haven't came across any in yrs now. Mose was studio shy. He would get in a studio and freeze. There was a guy I can't remember his name that came down here from Chicago I think. He set everything up in Mose's living room and recorded him talking and picking. They were great tapes I have no idea where you could get one now though.
