The weddings I would go to also ALWAYS, ALWAYS, ALWAYS (and I do mean ALWAYS) played the stupid 'Electric Slide.' Gawd, how annoying! It was like THE song that everyone would always hop up and dance to. After so many times of hearing it I would cringe when they would start it. Usually I'd find myself on the dance floor and then as soon as it would start and everyone was jumping up to come to the dance floor I'd sit down. Man, it was so annoying. Then it turned into the 'other' electric slide...I don't know what that one's called, but where it says '...Now Slide to Left....Slide to Right...' I would just sit there in bewilderment. It's so funny now to think of it. Still have Electric Slide phobia though. LOL!
Also at JW weddings: No bouquet toss, no garter, no dollar dance ... translation: no fun
Sometimes some with some more $ sprang for a Latin band. One wedding I went to had a pretty famous Mexican local band and the place rocked. The whole place was jamming and we all had fun.
