Do you need the sheet music, lyrics or chords?
It’s a wonderful tune. There are lots of internet resources for bluegrass tunes and songs. I just need to know what exactly you’re after.
I sure didn’t have any luck. I wonder if it is under copyright? After I found the lyrics I knew what song it was. I’ll be interested to see where somone finds it. Also a bit humiliated. If you have a recording, I think it wouldn’t be too hard to pick it up off that—since it’s not real fast—if you can’t find the sheet.
The commonest format to fine tunes in in the bluegrass universe is in TAB–tablature for playing guitar, mandolin or banjo.
If that’s what you can find, it’s possible if you want it badly enough to work out std notation (and hence abc) from tab. I think there are programs which can do that, as well.
