I was in a number of "Folk Mass" groups through the 1960s and 1970s. Then id didn't do choir for a while because I was too busy holding kids during Mass.
But then I joined a choir in 1986 and have been in choirs continuously ever since. I joined the 1986 choir after it had somewhat settled down into conventionality. I understand that the choir was once named "Morning Train." I also heard that they used to regularly perform Hoyt Axton's Joy to the World. Not the bullfrog version, though. It's my understanding that Axton wrote these alternate lyrics:

Jeremiah was a prophet
Moses was a prophet too
Jesus was the Son of God & man
His love shines down on you....

Joy to the world
All the boys & girls now
Joy to the children of Galilee
Joy to you & me

Now, this is not something I have been able to verify....


They also sang a version of "All Through the Night" that had the line:

Christmastime is so appealing...

There's no accountin' fer taste sometimes, ya know.

Oh, yeah, and I did hear attempts to Jesusify "I Will Follow Him" that Little Peggy March recorded.
