One of my favorite songs, from one of my favoritely-named bands, with one of my favorite mondegreens:
“Dance Hall Days” / Wang Chung (1984)
Listen carefully to the refrain: We were so in phase in our dance hall days… We were cool on…
Wait, what? Cool on Christ? Nope. It’s apparently “cool on craze.”
I like mine better.
the sloppy copy 
I totally always thought it was “Cool on Christ”! I will continue to sing it that way.
As will I. It doesn’t make sense to me the other way. It also doesn’t make me giggle.
