Chord/Tab song: Ballad of Arizona

Intro: Dm Amaj7 Gmaj7 F Amaj7

Well the [Dm]wind doesn't blow and the [Amaj7]flags don't fly

The [Gmaj7]ships take their seats and let the [F]clouds sail by[Amaj7]

And [Dm]all of the carousels [Amaj7]whisper a tune
( Tab from: http://www.guitartabs.cc/tabs/l/la_rocca/ballad_of_arizona_crd.html )
As [Gmaj7]Indians meet cowboys on this [F]April afternoon

I don't [C]know what you want, I don't know what you want

And [Gmaj7]neither does your pioneer[F]

I don't [C]know what you want, I don't know what you want

And [Gmaj7]neither does your musketeer[F][Amaj7]


Rest of the song is the same. There's a harmonica solo but who writes that on a
guitar chords section? How DO you write a harmonica solo? :/
