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.)
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.
