The title is incorrect -- it is "Diesel on my Tail".

Words and music by Jim Fagan

Recorded by Jim and Jesse McReynolds in 1966, a top-10 hit. Ian Matthews did a good version on the Plainsong album. And from memory, I think some of the words he sang were different:

Verse four, last line should be "For this doodle bug could never stand the jar".
The "two of us" is sure to be a mondegreen (mishearing). This is borne out by a Google lyric search (see Del Reeves) and by listening to J&J.

In the final verse, Matthews sings "While I'm tremblin' and a shakin' he's a blowin' on the horn", but this is probably his own change, as J&J definitely sing "pouring on the coal".

It would be good to get this corrected in the DT.
