I had some time this morning so thought I'd post links to selected YouTube videos uploaded in the last seven days:
The first reveals something I was unaware of, Myron Floren could play concertina!

The April tune of the month "Waltz from Boda" - (perhaps listed elsewhere on this forum?)
Concertina by the campfire - Little Brown Jug
Can't see the concertina, but I thought this was worth a look for the vocalist.
Einstein and the Concertina
If you want more:
I don't know quite how to catagorize this one, so I'll just say it's very unusual. Aside from the sound track, a concertina does make brief appearances at about the 3 minute point, again twice around 4:20 and at the end. Not my kind of music, but I wish I knew what this was about.
Perverse Person Concertina

The Fabulous Gen Echo Open Band (includes concertina)
From the 2012 Bath Folk Festival
The Flying Toads
Juneau Folk Arts - On a Baritone English
I admit this one is a "ringer" (not the kind of concertina this forum is home to), but I included it in admiration for the enthusiam and hardiness of the player, on a parade float in what is clearly very cold weather. The first minute of the video centers on the player.
