Zampogna a Paro with double-reeds?

UPDATE: I just listened to that Compari Tigani (http://www.youtube.com/watch?v=AV7CDK7PBIY) clip like 15 times with my bass guitar and was trying to tab it out, unless I'm crazy it sounds like the bass chanter is playing F-G-A-A#-C and the high chanter is playing an octave higher at E-F-G-A-A#-C. Someone please corroborate me on this before I go insane.

Regarding the A Chiave from Southern Calabria, this is the instrument I am referencing just to make sure we are talking about the same thing. http://www.youtube.com/watch?v=AV7CDK7PBIY As far as I know, it is tuned the same as the northern a chiave pipes but with the third drone playing the tonic note of the bass chanter (Sean can you tell?).

I'm hearing 3 drones : F, C, f'.
