On the Amazon - guitar chords and comments

Lyrics without distraction HERE

This frantic song, stuffed with foreign words and insanity, is from the 1928 musical "Mr. Cinders" and sung by the character Jim Lancaster. Responsibles for this were Vivian Ellis (composer); Clifford Grey and Greatrex Newman (libretto, arrangement). Columbia released a 78rpm cast in '29 with Jack Payne and the B.B.C. Dance Orchestra.
For funny reasons, Don McLean came across this one, and included it with his self-titled album of 1972, as the only song he hadn't written himself. In -76 he performed it live for the double-album "Solo".
Especially live, he performs tricks and chords I can't neighter figure out nor recall. Why should I? This "straight" version is crazy enough.
Am                E7   Am              E7
there's a danger zone  not a stranger zone
Am                Dm            Am             E7
than the little plot I walk on that I call my home
Am             E7      Am                E7
full of eerie sights  weird and skeerie sights
Am             Dm           Am         E7        Am
every vicious animal that creeps and crawls and bites
G ...Fdim ... D7sus4
on ...
        C6+2  Am          D7sus4   G
... the amazon the prophylactics prowl
       C6+2  Am        G7/9
on the amazon the hypodermics howl
       C6+2  Am             Bsus4            Em Gdim Dm           G  
on the amazon you'll hear a scarab scowl and sting   zodiacs on the wing
        C6+2        Am          D7sus4  G
all the stalagtites are vicious vertabrae
         C6+2       Am           G7/9
hunt the stalagmites while laryngitis slay
         C6+2     Am             Bsus4          Em  ...Gdim...Dm...G
all the parasites that come from paraguay in spring
         F         Fm                 C Bdim A7 
snarling equinox among the rocks will seize you
         D               Dm              Fmaj7 Cdim G
and the fahrenheit comes out at night to freeze   you
      C6+2  Sm             D7sus4   G
wild duondenum are lurking in the trees
         C6+2     Am               G7/9
and the jungle swarms with green apostrophes
       C6+2  Am   F  G    C
oh the amazon is calling me
