I've put a drum intro for a couple of bars then the simple chord pattern (B to A) before the verse for a bit of improv. Although the verse is just B to A repeated 6 times I've written it out in full since I often print out to pdf then annotate that to insert lyrics, I have used a 4x repeat on the chorus though since they just sing Fire, fire on the mountain four times.

The Pop Funk with 2/2 actually gives a feel remarkably like the tune (did mickey hart have iReal? ;-)

Fun to jam along to.
