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,
G# B
Buy ribbons for your hair.
C# F#m
You need me anyway
G# 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.
