I'm doing a bit of research into singsong-type music traditions (at the pub, party, back of the bus) and it strikes me that in their sometimes free-for-all chaos they could be compared to what is commonly called an 'ugly' in folk club/festival circles.
Would anyone care to hazard a definition of what an 'ugly' is? And why it is called an 'ugly' - ugly sound, ugly sight (?). Is it that they're just not 'beautiful' like a well-crafted stage performance?
Lastly does anyone recall when this term first appeared?
