The chords of the song are the following. I think that Donovan played the song with a 
a second down (DGCFAD), in that case play E A B instead of D G A, and so on.


D                    G
All the boys in the neighbourhood
D              G       Gm
would love you if they could,
        D   G A
but I'm easy,
        D   G A
but I'm easy,
        D   G A
but I'm easy.

Now that you're in demand
handle it if you can,
'cause it's easy,
'cause it's easy,
'cause it's easy.

C#            F#m
I'll take you anywhere,
Ab           B
Buy ribbons for your hair.
C#            F#m
You need me anyway
Ab                C#m B      A
And you know what I'm going to do.


Now the boys as you look about
may be funny to work out,
but I'm easy,
but I'm easy,
but I'm easy.
