Drunken Georgian lads = singing

I really love Georgian polyphonic singing and I also really love how Georgian's sing at every opportunity. I remember when me and William were there in 2007 we were serenaded by friends of friends in a park and sat in on teenage boys learning traditional song as a matter of pride. I also love how in these clips they are managing it whilst really drunk and chain smoking... I can't help but wonder if British boys sung more we'd have less fighting and vomiting in the streets on Saturday night... Having said that Georgian men fight more than any I've ever met so... maybe this is a silly point. The clips are quite funny though...
