I just randomly stumbled across this video recently. It looks like it was also featured on NPR, so I'm not sure how I missed it there. Anyway, it's Lisa Hannigan (who I might need to learn more about). She has an amazing voice and she's Irish. So, that's a win/win. Oh yeah, and she plays ukulele!
I guess they filmed this video in Dublin and they did it in one take. Once you see the video you'll see why she might have been reluctant to do a second take. It seems like they start off having the different paint represent different instruments but then it sorta goes haywire. Anyway, it's a nice little song, even if the ukulele isn't the main component.
