Hi Bolleauxp, I've played this song at times....that line has always been confusing. The way I play it is:
1 1 2m 5
meaning: G G Am D (if your playing in the key of G)
and this works for me sitting around the living room jammin. I'm not real sure how to put this but I think that the {5 2m} {Em 5}, they were trying to follow the vocalization at that part of the song. I hope this helps, by the way, I got to see the Bellamy Brothers several years ago in Vicksburg, Mississippi at one of the riverboat casinos. They were fantastic!
