I play it in A.

I asked my [A]love
to take a [E]walk
take a [E7]walk
just a little [A]walk
down be[A7]side
where the waters [D/F#]flow
down by the [A]banks [E]
of the Ohi-[A]o

The picking pattern (on A) is:

  1  and  2  and  3  and  4  and
  T5  I3  T4  M2  T5  I3  T4  M2   

(substitute T6 for T5 on the 6 string chords)
