Hi, CaptainC-
Can you post the lyrics so people can be sure we're talking about the same song, and so we have the song for our archives?
I believe Alan Block and Don Hecht wrote the song titled "Walkin' after Midnight" that Patsy Cline popularized and everybody and his brother has recorded - and that isn't the song you're looking for.

BMI.com does have a listing for the song, but I don't know if this link will work - click.
There's not enough room for such a long title, so it's listed as:

WHEN YOU GO WALKING AFTER MIDN (Legal Title)

BMI Work #3850868

Thanks.
