I've seen bands playing live music at international conventions, musicals, dancing with the JW literature cart. JW's dressed in big cardboard cut outs displaying wt literature while dancing/singing. Little children acting out inappropriate bible stories (like the Delilah story). While it sounds fun and entertaining, it seems they are getting desperate with some of their ridiculous antics.
@Joe134cd I will be looking up the phone waving thing, sounds more like what people do at a 'worldly concert'.
