Assuming anyone really wants an answer (and not just a a chance to whine about bad experiences), here are a couple of real examples. Oh, I realize that they are seldom where people WANT to sing, but they ARE great places to get better, learn to handle a mic, learn stagecraft, AND make a few people wildly happy:

<> Nursing homes
<> Senior daycare centers
<> Preschools
<> Mudcat gatherings
<> Festival INFORMAL song circles (campgrounds)
<> Church services (no you do NOT have the BELIEVE or act like it)
<> Campfires anywhere
<> Park benches
