One Man Band
Leo Sayer

       F (133211@1)     CSo (x32010@1)you move along all day
(Personally I would put the last part of the second verse here too, it's very effective)

                CWith (x32010@1)my one man band

(same first verse chords)
For three days now I havent eaten at all
My my you must be getting so thin
And soon my cap wont be large enough
To drop a half a crown in

So hey there mister dont you look so sad
Dont look so ill at ease
Well I can play you any song you like
To cheer up that life you lead

Well Im a one man band
Nobody knows nor understands
Is there anybody out there wanna lend me a hand
With my one man band


    F (133211@1)F* Dm (xx0231@1)           FAnd (133211@1)oh oh oh look at the rain falling
F (133211@1)F* Dm (xx0231@1)          GOh (320003@1)oh oh look at it rain
              COh (x32010@1)look at it rain

Well nobody sees the minstrel boy as he sings his tale of woe
Nobody sees him coming
Nobody see him go
So hey there mister dont you look so sad
Dont look so ill at ease
Well I can play you any song you like
To cheer up that life you lead

Well Im a one man band
Nobody knows nor understands
Is there anybody out there wanna lend me a hand
With my one man band

Well Im a one man band
Nobody knows nor understands
Is there anybody out there wanna lend me a hand
With my one man band

Oh Im a one man band
Just a one man band
Oh Im a one man band

It can also easily be played in G, but this is Leo's key.
If you choose G the drop at the Rain bit is a simple run down to Am.
But C has more feeling and character.
