This is a very easy to play song as it is only 3 chords. To make it sound like a tune 
a beat, try to incorporate some finger picking with string tapping.

Chords: [ch]Am[/ch], [ch]G[/ch], [ch]Dm[/ch]

[[ch]Am[/ch]]I need a [[ch]G[/ch]]dollar dollar, a [[ch]Dm[/ch]]dollar is what I [[ch]Dm[/ch]]need
hey hey
[[ch]Am[/ch]]Well I need a [[ch]G[/ch]]dollar dollar, a dollar is what I [[ch]Dm[/ch]]need
hey hey
[[ch]Am[/ch]]And I said I need [[ch]G[/ch]]dollar dollar, a [[ch]Dm[/ch]]dollar is what I [[ch]Dm[/ch]]need
[[ch]Am[/ch]]And if I share with you my [[ch]G[/ch]]story would you [[ch]Dm[/ch]]share your dollar with [[ch]Dm[/ch]]me

Bad times are comin and I reap what I don't sow
hey hey
..........

And so on, the chords are the same throughout. Hope you like it, enjoy.
