For I KNOW WHAT YOU'RE TALKING ABOUT, the best I can do is a partial transcription based on several sound samples:

...crowd passes by.
Some are talking 'bout their wealth and their riches.
Some are talking 'bout their troubles and strife.
I don't know how to talk like a rich man.
When compared, I'm a beggar no doubt.
If you're talking about that old-time religion,
Then I know what you're talking about.

If you're talking about that old-time religion,
Then I know what you're talking about:
'Bout the kind that will make you love your neighbor
When old Satan would say, "Turn him out;"
'Bout the kind that will comfort you in sorrow,
And it never fails to make you shout.
Well, if you're talking about that old-time religion,
Then I know what you're talking about.
