Paul ButterField - Done a lot of Wrong Things

[Warren <wkeane@xxxxxxx>]

Howdy, 

I think the harp in that Paul Butterfield did on the song 'Done a lot of
Wrongs things' is some of the most beautiful that I have ever heard.
Does anyone out there know the harp and position that Paul was using to
do this?
It sounds like key of F to me but I don't think it is in 2nd position on
a 
Bb harp.

Thanks in advance.
