Just for clarification

Tim Eady is English

The tune is not "Irish"

And I believe he is playing a Saltarelle Nuage in a 5th (4th) apart system.. my guess D/G..

An "Irish" tuned box would be B/C,C/C#,C#/D,D/D#

He mentioned he was going to play with Brendan Power.. a phenomenal harmonica player from New Zealand I believe...

I also understand that Eady may be messing about with
B/C box but due to the fingering and the chords I think it was a D/G
His self titled C/D was in D/G

Note that also on youtube you can see him play "melodeon" the one row accordeon..

excellent player in may styles...

Also plays guitar and piano
