I have some preferences on the playing of the _chords_ in 'Melissa' that
differ a bit from his, which I think you'll find easier to play (and maybe
even sound better):
(excuse the lack of rhythm & timing, but I think you can figure it out)

This song is REALLY meant for a 12-string - with all that open-string
resonance, it really rings!
Hope this gives you more of what you're looking for!
