The Bee Gees were very good as they had the discant thing like no one ever did. I mean with the high voices they could have an incredible range.

By the way, I've put a message for you up in the welcome center as you're a post 5000th member so welcome in any case! But I'm glad you've put your first post here in this thread. We have a rather, spirited group in the music section.

If you don't, you stick out.
