for the original tab I saw.) Riff 1: Notes: Riffs 4 and 5 are played as backing on the First and Last and Always disc, and they're also played by a keyboard. However, on the "Knocking on Heaven's Door" bootleg, at least, the lead guitar plays them. If you only have one guitar and no keyboard, they add a little variety to an otherwise very repetivitve song. Bass riff is what's actually played. However, Frank does the vocals as well as bass, and riff is a little too complicate (guitartabs.cc)
