Laura Ingalls... yes... that is fun to do... singing with family. We aren't at the point where anybody else (except me) can do the parts together...3 little boys and a 12 year old who doesn't reall have a clue either.

Oh well, we can still try.
Steve: LOL, my goodness! Hard-core screaming!? LOL. Your family must looove it.

Look up vocal warmups on Youtube, there are GAZILLIONS of them.

I use those a lot though I already have a vocal teacher who IS a HUGE blessing.
Shennifer: Choirs are very fun indeed. I am in a church choir right now but... well... it sure *ain't* anything professional! But as long as it's about praising God, it doesn't matter! Recording a CD sounds great too... that would be real fun.
Jesus' Princess and Termite: singing for fun is definetly a great thing to do... deff. more relaxed than singing in front of your teacher, and thinking you sounded terrible because it was your literal worst time of day to sing. (We all have those, you know.)
