Im sure there were many of us used to sing corrupt words in hymns,(particularly in Christmas Carols)

eg ....his first avowed intent to be a Grimpil (Not pilgrim).

Hark the herald angels sing, 'Beechams Pills are just the thing'

We three Kings of Orient are.
Selling chocolate, tuppence a bar,
One in a scooter, blowing his hooter,
Following yonder star

While Shepherds washed their socks by night,
And hung them on a line,
The Angel of the Lord came down,
And said 'Those socks are mine'

There must have been others .........

Something similar to;

While shepherds watched their flocks by night
All seated round the pot
The Angel of the lord came down
And scoffed the f.... lot

Versions current among the choristers at St Mark's, Utley, in the war years:

While shepherd washed their socks by night
All seated round a tub,
A bar of Sunlight Soap came down,
And they began to scrub.

and . .

Good King Wenceslas looked out
On the feast of Stephen.
Something hit him on the snout;
'Twas a red-hot cinder.
Brightly shone his nose that night,
Though the frost was cruel;
When a poor man came in sight
Riding on a rusty bike.
