This is a great melodic version of Wheel Hoss. Most of it is pretty straight forward. You need to watch out for the measure of 3/4 in the B part. After the last D Chord, the beat starts over on one, instead of finishing the measure on G at beat 4. It's tricky but an awesome signature of this tune. It's definitely one of the things that makes Wheel Hoss, Wheel Hoss.
Make sure to check ou the licks, there's several that are closely based on the fiddling of Kenny Baker. Bluegrass Boy official!
