Joe: Norm Cohen's Long Steel Rail is the most comprehensive train song book I know of.

I can't make much sense of Cohen's methodology in LSR given he's dealing mostly with 3-5 minute samples of verses (cylinder & 78rpm) when the songs run 15-30 minutes in the wild. There's no accounting for the practical majority of missing verses in any one so-called song 'type'.

I'm not qualified to speak on the entire pantheon of 900 Mile/Train 45/Reuben songs but, as for the Ledford's neck of the woods, this is the instrumental Old Ruben and when the verses are added it's Crazy Over You or just Crazy (mostly XXX Miles &c)

I haven't found any mention in Cohen to an inside West Carolina joke on the latter song title and Wade Mainer's radio sponsor Crazy Water Crystals (a laxative.) The title seems to have escaped Cohen's net altogether. Not an easy miss but… still checking.
