i used to believe that the song "we 3 kings" went like this:
we 3 kings of orient are
1 in a taxi 1 in a car
1 on a scooter blowing his hooter
smoking a big cigar

I always used to think in the Christmas carol "God Bless you and Give you a Happy New Year" they were saying, "And may joy come to you, and to your mimosa, too." I figured this was because grown-ups drank mimosa on Christmas morning, and the song was hoping their mimosa was yummy.

Instead of harvesting, I thought the people in the hymn were herding sheep. "Bringing in the Sheep..."

I don't know if this qualifies as a belief, but when I was real little, we went to a church where they sang out of the old redback hymnal. If you're from the south and you're Baptist, you know what I'm talking about. Well, back then I had an obsession with words, and liked for people to read the dictionary to me. I loved the way certain words sounded, but hated other words. For some reason, I hated words that ended or sounded like they ended with ATION. That's weird, but it sounded ugly to me. I have no clue why.
I would get so irritated in church when we sang songs that had words like that. I didn't like singing those words, and I thought someone should rewrite the songs. When I told my grandmother about it, she sort of chuckled.
Now I love those gospel songs, but every now and then, I think of that, and feel like a goofball. I'm glad nobody remembers that.

As a young woman, I never lived down being heard to sing - as a six-year-old - "Jesus bitches shine".

I always wondered what a "sino" was in "Jesus loves me the sino..."

I used to believe that we were singing "Rosanna in the highest" in church, instead of "Hosanah" and I wondered for many years why I hadn't heard of Rosanna anywhere else.

When I was six, I used to think the song "Deck the Halls with Boughs of Holly" went "Deck the Halls with Boston Charlie." I still sorta sing it that way to myself, 30 years later!

The Xmas song's line actually is "And good will toward man"... I thought it was "Anger will Demand". Mom and I still laugh about it!

aAt school we had to learn all the hymns by ear and in "All things bright and beautiful" I used to sing "How great is God or Mitty"!!!!

I wasn't helped by attending the funeral of a wealthy man who had chosen "Guide me, O thou great Redeemer." The order of service contained a misprint (accidental or otherwise) which replaced "Land me safe on Canaan's side" with "Land my safe on Canaan's side."
