Sorry Teddy for not commenting 
. I’m making up for that oversight.
While I’m at it, I’ll answer @Alexandre too 
.
Actually, I already knew this video, I’d even posted it the day before, in response to @Christophe_E, who was quoting William Burton actually 
So when I saw your post, Teddy, I just thought you hadn’t paid attention to it or that you wanted to highlight it more specifically, which is cool too .
Since I’m a pretty laid-back guy, I’m cool with the 6 hours of didgeridoo (though I’m not sure I’ll be performing well for 6 hours 
).
