We went to Van Morrison at the wiltern which is kind of a stuffy, lied center sort of place.  no one was dancing, but we HAD to...people were upset behind us for standing up at a rock-n-roll concert...so we tried the aisle...the ushers told us we couldn't dance there...so ro' went to the manager to find out where we could dance, she said dance in your seat, maybe you'll start a trend.
