Conundrum?

Recently, I've come across some questions involving worship ministries. I've looked at some blogg sites and some magazines and the topic of worship ministry vs. fine arts ministry. I read a magazine article that interviewed Randy Quackenbush (James River Assembly of God) and John Lindell (JRA). A couple of years ago, John and Randy made a switch from a worship ministry, to a the more encompassing title of fine arts ministry. This switch involved adding dance, drama, and other facets of art to the ministry, which Randy oversee's with the help of ministry leaders.

I guess my question is, how relevant are these ministries? Are dance and drama (along with other facets) valid for completeing the purpose of ministry, which would be converting and discipling? I offer no criticism of either of these two, at least not yet. I am just asking. Also, what other things could be incorporated into this area to be effective?
