Tough issue - many more bad courses of action than good. Let me tell about a different venue and a far different distraction. Earlier this year I went to the Big Muddy Folk Festival in Booneville, MO. On each of the 2 evenings, a concert was held in the old historic Thespian Hall. Many great performers were featured including Special Concensus, Otis Taylor, Gerry armstrong, Bok, Muir, & Trickett, Andy Cohen, Larkin Bryant, Bob Dyer, and of course Cathy Barton & Dave Para. Well during almost every performance the audience would instantaneously break out in short-lived murmur, stir, and giggle. The performers, except Cathy, Dave, & Bob, would very professionally continue their routine, but, nevertheless express a look of concern and bewilderment at the sudden burst of audience distraction. Well it was the famous Thespian Hall bats who were periodically making straffing runs over the heads of the unsuspecting musicians. After all this was there home.
