There are actually a good selection of Youtube performances and whole series of them like the Tiny Desk Concerts; Songs From The Shed Sessions and Narrowboat Sessions. Plus lots of individual performances from especially younger performers. Here are two that always brighten up my day

I always think this live performance is better than Paulo's official video

And if you're feeling down the sheer exuberance of this is sure to lift the mood
