What's worse than an earworm? An earworm you can't identify.

There’s part of a song going round and round in my head. I think I remember it from high school, but I’m not sure if it’s from a musical they did, or from chorus. Chorus, I think, since I seem to remember singing it. I’ve done a Google search, but nothing is coming up, so I’m turning to the Dope. Go back to the '70s or before, and please, please, tell me where this is from.
You can do anything, if only you’ll try.
Don’t alibi, just reach for the sky.

You can do anything, like dance upon air.
Be debonair or strong as a bear.

(That last line might not be right, but I think it’s close.)

How about an earworm of a song you don’t even know the words to?
I’ve got two of those that pop up occasionally.
Like, uh, now . . .

Sorry. Didn’t mean to start something.

I think I found the song that matched the lyrics you posted. It is “Under” by Breaking Point. I have attached a link to the song on YouTube and lyrics are shown in the “Show more” section.

I love a good scavenger hunt. In searching for some earworms, I happened to see your post and took it as a challenge. Hope this is it.

Have a great day!

That happened to me for 20 years. I kept hearing it every now and again but could never find out what it was.

Eventually it turned out to be a Brian Ferry song …

Al Bundy had the same problem.
