Interesting, and I am still not done reading but I wanted to comment before I forgot. We did the same kind of stuff -- we had a traveling youth choir and would peform contemory songs of the time. I remember we did Petra's Grave Robber, How Majestic Is Your Name, Friends and a few other MW Smith and Amy Grant tunes. We would go to camp and do similiar things with VHS tapes. I can even remember the SAME Billy Joel song being played in church, an instrumental version on saxaphone and the theme of it was "Just The Way You Are" as being a spiritual song. Not only that I remember the church musicians doing "Taking It To The Streets" by the Doobies and the message was "we need to take the message of Jesus to the streets".
My youth pastor, Jeff, was also in a Christian Rock band. They were similiar to Crowded House, Husker Du or U2. Someone set up a page for them here and it was nice to hear their tunes again:

Check them out if you are curious. They used to practice in our church gym and allowed me to sit and listen. The drummer was my youth pastor. My second year of college he ended up leaving the church and left ministry altogether as far as I know. I believe he is now a counsler for teens at a halfway house.
And those NBA games -- classic! I can remember watching The Pistons and The Blazers on a small, battery operated B&W TV that I took with me to camp (mentioned above) so I could watch the game that night! As a Pistons fan I was excited and also had new respect for the Blazers. Some classic match-ups back then!
