The song you are all trying to think of is "shout to the Lord" realised around 1990.
Hill song is something that I have not been to and proably won't ever go but that has more to do with me than it. I know oh 20 or 30 people who have been and am very familiure with the music, the schools you are talking about are I think something that has been being run as an exersise in equiping the church (universal) for worship.
The only complant that I have heard about this group is that it is a true dyed in the wool mega church, with Epos swip cards under the seats and that one gets a bit of a cold shoulder from the mass of people their unless you know someone. Not bad just cultural, churchs always seem to pick up culture.
Music is great (if a bit soppy) and the events run by these guys that I have been to have been great (there was this thing called count down 2000 they did way back when-that was cool).
Nah go for it alacia and if you get the chance head west over the mountians and expericance the dry place that is actually rather alot like SA. (Same sought of climate and the some colours of green and brown or so my folks tell me)
