This is just beautiful.
I actually have a thumb piano, I believe the one he is playing is a Kalimba; one with far more notes than mine has (four).
It sounds a bit like he’s going to do the McDonalds ‘badababaya – I’m lovin it’ thing at the end! Interestingly someone once told me that all McDonalds employees are contractually obliged to sing ‘I’m lovin it’ back at you, if you go up to them and sing ‘badababaya’. Of course being the sort of person I am, I tried it.
It’s not true.
