I dont blog YouTube ukulele videos anywhere near as much as I used to. Simple reason is that YouTube is awash with bedroom recordings of Jason Mraz and others, and its quite hard to find something really nice in between it all.
Then I fell across this video of a duo under the name of Ka1a1aika covering this Yann Tiersen piece from the soundtrack of the film Amelie (also one of my favourite films which helps).
I think it is really rather lovely. Uke spotters, that is a Kanilea K1T and a Kala solid Acacia tenor)
