+3 for easier chords...and I think the interlude is supposed to be the same chord progression as the verses

-2 for simpler chords

Note to Self... - Sub E7 - Add Gsus4 after final G in each phrase (it'll look like this: G Gsus4 G Gsus4) - Strumming (D DDU) (D DDU) (D D UU UDU)

+2 Riff: A | 2————2————-|-2——————————0–| E | ——3————3——-|———-3—————–3—---| C | –2——2——2——2-|——2——–2–-0-–3——--—| G |——————————|——————————--- |

I've been using D DU UDU pretty much the whole way through except for the "E" (BTW...E7 sounds fine here and may be easier to play); where I do D D D D for emphasis.
