Hi, sorry I'm so late to the party

The song to my Covid-bound ears seems 4/4 all the way through with three ¼ beat rests added per run-through.
Iimmediately before the Part C there is one rest, and at the tail of Part D, including the repeat, there is also the rest. I've tested my perception multiple times, with and without coffee, and it comes up consistent.
I'm basing this on the 1975 Kenny Baker recording. When Bill comes in with his mandolin, he is playing a high note through the rest but if you count the rest then begin with 4/4 again, it works out perfectly all the way through.
Bill and Kenny were tricky guys. Brilliant phrasing. vThere is nothing to imply a 3/2 measure or a 5/4 measure. Just the plain ol' ¼ beat rest thrown in there.
It takes some getting used to, but if you count 4/4 and throw in the extra beat at those moments, it all works out consistently.
Love the F# Kenny plays in the first measure of Part A. Naturally, as it should be sharp I'm sure. that is the way I play it.
Great to be here. Sorry I'm late. - The Woodman
