I see the folk process has been to work on this one! Following are the correct lyrics, by consensus of several web sites. Differences are marked with italics.

WALK ON BY
(Kendall Hayes)

If I see you tomorrow on some street in town,
Pardon me if I don't say hello (say hello).
I belong to another. It wouldn't look so good
To know someone I'm not supposed to know.

CHO: Just walk on by. Wait on the corner.
I love you, but we're strangers when we meet.
Just walk on by. Wait on the corner.
I love you, but we're strangers when we meet.

In a dimly lit corner in a place outside of town,
Tonight we'll try to say goodbye again (goodbye).
But I know it's not over. I'll call tomorrow night.
I can't let you go, so why pretend? CHO.

[Recorded by Leroy Van Dyke, 1961.]
