Ultraviolet is a wonderful song from U2's hit album "Achtung Baby". I was 
listening to it and thought it would sound great on an acoustic, so I played 
around with some chords, this is what I got; a simple 4 chord progression. 
NOTE: I did not include the opening/intro!

G (320003@1)       D (xx0232@1)
