I just stumbled upon this thread myself and was immediately reminded of an incident that occurred earlier this year. Every February, a friend hosts an acoustic open-house, opening his home to any and all musicians who end up song-swapping and jamming in every corner of the house. Over the years, rooms seem to adopt one characteristic or another...bluegrass in one, Cajun/Zydeco in the kitchen, Celtic up the stairs, etc. One room always tends to '60s and '70s folk/folk-rock/rock with the participants trading off songs equitably and appreciatively. However last year, some Paul Stuckey wannabee planted himself in the middle of the room with a music stand and a stack of Weavers/Kingston Trio, etc. songs which he plowed through one after another without letting anyone else get a note in edgewise. What is ususally the most popular room at the event devolved into a one-man jam consisting soley of Mr. Folkie, oblivious to the fact that he'd chased everyone else away. Not that there's anything wrong with that genre, but, sheesh, give someone else a chance.
