[Harp-L] Organ key in "Help Me"

["Ken Brocx" <ken.brocx@xxxxxxxxx>]

Hi,
So this is my first list question!
In Sonny Boy Williamson's song "One Way Out" there is an organ playing in
the background in what I suppose is a minor key.
If I wanted to play that organ part of the song can anyone tell me what harp
and key I could use?
Lee Oskar Natural Minor or Harmonic Minor maybe?

Thanks!
