Charlie Musselwhite harp on Tom Waits song

Hi David,

I was wondering if you know what harpswitch Charlie makes on " Puttin  on the dog " by Tom waits 

Song in Amin , he starts on third position in the intro and then goes to some beatiful warbles ,thought it was on the low d harp but that's not the case .Allthough he uses that too in the song .. Fifth position?? Great harp work for sure !

Thanks David !!
