our Jam that we have in mt.airy,n.c., is a "round robin" affair...
you are numbered as you get there and so on...
and,you get to perform one song each time,unless you are part of a duet or trio...
but it works fine every week and has for over 15 years now!
most of the weeks i've been there each performer gets at least 3 times at the mike in a two hour show...
