Church or Show Business?

I started thinking the other day about the way in which the church nowadays has become very music oriented with all the good and bad things that are related to it. I assume it mostly started with John Wimber in the 60s who as a professional musician wanted to write good songs and play good music in a church context and that seems to be a good aim.
This led me to thinking, how far have we taken this? Can we no longer have any church meeting without music? Do we do it because it is an easy low cost way to make people feel comfortable or happy or worshipful in meetings? If we subtract the music and an obligatory sermon we are left with roughly nothing. What about all the other parts of church life? Prophecy, encouragement, charity, evangelism? Spiritually speaking, music and teaching are easy to do. They have little real cost and can be faked easily enough if we are not actually annointed to do them. Other gifts that we conveniently push to the sidelines require us to engage with God or other people and these are much harder to do. In evangelism, although we can pretend to be annointed, if we are not then it won't take many rejections or lack of 'results' to provide an excuse to jack it in. Prophecy won't last long if we get it wrong. Even general charity and encouragement require a spritual energy that is not easy to fake over time.
I was also thinking about the big events that we like to do with churches in the West. Some of these attract thousands of people and often they cost large amounts of money which without being too killjoy could be funnelled into more deserving projects. I understand the logic of "people are encouraged by these events", which seems to be the most common justification of the events but the implication of that comment is that if people are encouraged (because it is big and fun and there are lots of people etc), they will always be encouraged and therefore we should always run the events - there is no real space for God's opinion.
A few years back I heard that New Frontiers had stopped running the Stoneleigh Bible Week despite massive support and popularity. It was refreshing that people had put their faith before the 'logic'. I'm not sure how many of us would have done the same.
I am often troubled by the egos that get polished at these events. It is often about a few very highly regarded speakers or 'worship leaders' teaching to several thousand listeners which doesn't seem very much like Church. What about everybody being able to exercise gifts? What about the fact that just because somebody has been annointed to teach in the past doesn't mean God won't decide to use somebody else in the future. The marketing is full of 'Speakers include John Smith and Charlie Brown' as if these names are selling the event! Shouldn't it say something like 'We believe God wants to use this event to encourage and teach you' and not bother with the 'names'?
The other flaw in the encouragement logic is that the big events can have the opposite effect. They feel so great when you are there that normal church life seems tedious or lacking even if it isn't. You can't have the buzz permanently so won't it make you feel like you are missing out for 51 weeks per year? I'm not even convinced that much equipping takes place because equipping is about a person engaging with God and if they can't do that away from the big events then nothing much will come of it. Sure there are life-changing events but these happen in many contexts outside of these big events.
I'm not sure. I keep wondering, is this Church or Show Business?
