is this the holy grail of tv theme lyrics?

For a long time I was under the impression that the closing theme from WKRP in Cincinnati was a bunch of gibberish. For reference:

Now there was a time that I just assumed there were reasonable lyrics that made sense, but I had no idea what they were. Then, at some point, I read on the intertubes (and you know you can trust anything you read there) that, in fact, there are no real lyrics. It was all gibberish that was made as part of, I guess, some kind of concept demo. Believing that, a lot of people have made unserious lyric videos with words that clearly aren't the words, but sound close. For example:

But tonight I saw a blog that seems serious and makes a reasonable-seeming claim about the actual lyrics.

The lyrics, according to the blog (OK, I made a few changes) are:

Said to the bartender
"Best night I ever had"
Singin' to the bar
Had a microphone in her heart
I said "Goodbye madam"
I had a bird in hand
I said I'm doing good
And put love in her heart

Listen to the theme while reading the lyrics. It sounds like these lyrics, and these lyrics make sense. Could they be the real thing?
