So true, Bill !!!
When we had our band in NY (and I realize it was in another era) we would have brides-to-be and family members dictating what they wanted played and then the night of the wedding the guests would have tons of different requests ... I remember one bride who said "No line dances" ... when we got the requests for 'The Chicken Dance' etc. we just told them to ask the bride ... invariably the bride would give in ...
