Chords for The Cathedrals - O Happy Day

You and I both went to a school of music called Stamps Baxter School of Music in Dallas, Texas
to learn how to read the shape notes.
And since a lot of people here are choir directors, music directors,
maybe some of them have never heard a quartet sing a song and do the notes instead of the words.
I'm going to throw you guys a curve and also the producer of this show.
Well, I never have heard of _ him.
Well, I guarantee you Doug Oldham can do it sitting back there.
In fact, Doug invented the shape notes.
But, _ Roger, let's do a verse and a chorus of Oh Happy Day
and do the Do Re Mi's to your part instead of the words.
_ [Eb] This is hard to do because everybody goes a different direction, but let's tackle it.
[G] Now, [Cm] don't say no words.
Say the Do [Eb] Re Mi's to your part.
