I don't know if these are the official chords or ones I made up - they're fairly simple but they work. The song is in 3/4 time, I'll use "/" to delineate measures, "//" means repeat same chord.

verse 1 (back when this earth...) A/D/G/A//D/G/A/F#m/B/E/A/F#m/B/E// verse 2 (down in the African..) A//G//A//G//A/G/D/A//G/D/A verse 3 (oh the crown...) same as verse 2 verse 4 (dory man he knows..) same as verse 1 verse 5 (it's the same...) same as verse 2 verse 6 repeat first verse but end with G/F/E/A
