Since the Bible record of weddings does not stress music and dancing, should this not guide a couple who plan a wedding that will honor Jehovah? Yet, in preparation for several recent weddings in southern Africa, Christian youths who were chosen to form part of the bridal party spent long hours practicing complicated dance steps. For months an inordinate amount of their time was used in this way. But Christians need to ‘buy out the time’ for “the more important things,” such as the evangelizing work, personal study, and attending Christian meetings"
Now after reading that article, can you imagine that "for months an inordinate amount of time" was used for them to learn those loud worldly songs? Shouldn't they have instead been 'buying out the time' for 'more important things' such as field service?
The amount of time consumed by all the practice, prep, etc. was one of the main things I thought about in conncection with all this International Convention entertainment stuff. The drummer (evidently the leader of "The Theocratic Revue") actually said they spent many hours practicing.
To answer your question, Yes. If JWs are what they say they are and if they truly believe that the end of the world is imminent and that billions of lives are at stake, then they should be very seriously and urgently using all available time to warn the world - not using their time frivolously. They don't act like a people who think billions of lives are to be lost at any minute, perhaps in a few months (as evidenced by the statement that this past Memorial might be the last).
