I knew nothing about the tremolo harmonica, which looks like a terrific choice for Irish music
Some nice harmonica playing:

Nice piano accordion stuff
Scottish Accordionist - Sandy Brechin (video)
One of my favorite pieces from the Callan Bridge CD,
“Muireann’s Jig” Cillian & Niall Vallely with Alan Murray;

Charlie Harris and Jackie Daly on accordions, the McGuire brothers Manus and Seamus of fiddles, from 1985, I believe.
Tunes are “The Tap Room / The Moving Bog / The Lilies In The Field”.
Joel Andersson plays an English concertina AND a harmonica AT THE SAME TIME
This is amazing !!
Video fluoroscopy (a low dose Xray video, in other words) of harmonica playing: shows what the soft tissues of the mouth pharynx and larynx are doing when you play various notes on a harmonica (including bending notes)
Where do the reeds go if it’s solid? 
It is a lovely box though, it’s true. If only buying one would enable me to play like Jamie.
