This is weird (at least, I don't remember hearing these), according to a lyrics website, the lyrics to the 1989 London cast recording go like this:
Times have changed
And we've often rewound the clock
Since the Puritans got a shock
When they landed on Plymouth Rock
If today, any shock they should try to stem
'Stead of landing on Plymouth Rock
Plymouth Rock would land on them
In olden days, a glimpse of stocking
Was looked on as something shocking
But now, God knows anything goes
Good authors too who once knew better words
Now only use four-letter words
Writing prose
Anything goes
