Chords relative to tuning. Simple but fantastic song! Listen to the song for strumming patterns. 
Can be played in standard tuning easily enough. Capo 2nd fret G = E, C = A, D = B

ENJOY! 

Intro

G - G - C - G - G - D - G - G  (x2) 
  
[G]Drifting, drifting, [C]drifting [G]away
[G]I got myself a mansion, then I [D]gave it away
[G]It's not the world that's heavy, just the [C]things that you [G]save
[G]And I'm drifting, [D]drifting [G]away

[G]Drifting, drifting, [C]drifting [G]along
[G]I rid myself of worries, and the [D]worries were gone
[G]I only run when I want to and I [C]sleep like a [G]dog
[G]I'm just drifting, [D]drifting [G]along

[C]The suitcoats say, 'There is [G]money to be made.'
[G]They get so excited, nothing [D]gets in their way
[G]My road it may be lonely just [C]because it's not [G]paved
[G]It's good for drifting, [D]drifting [G]away

::HARMONICA SOLO:: (same progression as "Suitcoats say...")

[C]The suitcoats say, 'There is [G]money to be made.'
[G]They get so excited, nothing [D]gets in their way
[G]My road it may be lonely just [C]because it's not [G]paved
[G]It's good for drifting, [D]drifting [G]away

[G]Drifting, drifting, [C]drifting, [G]along
[G]I feel like going back there, but [D]never for long
[G]I sometimes wonder if they [C]know that I'm [G]gone
[G]I'm just drifting, [D]drifting [G]along
[G]Drifting, [D]drifting [G]along
