I did a bit of research on the 'net for this and it appears that Kenny Baker and Bill Monroe wrote this together, or at least Kenny helped Bill write it. If you pull up the "recorded" version here

(as opposed to the "live" version links above), you'll find that, as megafiddle says, there are several places in the song where there's an extra beat in the bar.

I pulled the version I've shown here into the ACW and the first "long bar" (i.e. 5/4 if you're counting in 4/4 time) is at bar 22 (I believe).

The ACW will let you set any bar to (almost) any time signature, so it's fairly easy to line up the .wav file with the BIAB chord sheet in the ACW. However, when you "send to BIAB", there's no provision in BIAB to create a 5/4 bar. You would have to create (say) a 4/4 bar plus a 1/4 bar to get things to line up.

Good luck!
