What can I tell you … learn all of the riffs…you’ll discover the best fingering, when you get the pattern its pretty cool.
RE the bridge … if its just you playing, leave the capo on and follow the tab … if you have a 2nd guitarist, have him play bridge w/o capo … MUCH better because its up the neck
Here it is in G and in Earle’s key (CAPO2)
During the bridge, if you have compression AND distortion, let er rip!!!
Here’s Steve’s version last year, live
And an early live in Nashville version
