This one is really quite easy, it's just 3 Chords over and over.

G - A - D


as in

                 G       A        D
You talkin bout Lion - Iron - But you caan go to Zion
                 G       A        D
Chattin bout    Lion - Iron - But you far from Zion


..and so on. The verses are just the same. Of course you strum this one Reggae-Style. Have fun.
