I think the reason I hear it as AABB is that it has two 32-beat sections: one that starts on the IV (I think -- I don't have an instrument in front of me) and one that starts on the I.  And each of those sections divides into two 16-beat sections, each of which start with the same ~8 beats before diverging.

I learned the tune by dancing to it and playing it, though, so I don't know how it would typically be written down.

Jeff,

Based on how I hear the tune with my not-very-musically-educated ears, I can understand why you might describe it as AABB (with the A and B parts both having first and second endings). But if you happen to have published sources for the tune, I'd be interested in knowing whether they notate it that way.

At about 2:00 tablature appears in the upper right corner for what the narrator describes as "measure number one." The time signature isn't shown, but from the beaming of the notes, I'd infer that it's 4/4. In any case, each "measure" of music in the tablature includes what contra dance writers and callers would typically refer to as "four beats" or "four counts" or "two measures" or "two bars" of music.
