Mountain Music

In music class the kids are learning Mountain Music by Alabama. Previously they've learned Rocky Top and Country Roads. I sense a WV theme here. I'd forgotten about Mountain Music. It's been fun listening to Chloe and Owen sing it. Here's the chorus :

Oh, play me some mountain music, like grandma and grandpa used to play.
Then Ill float on down the river to a cajun hideaway

Drift away like Tom Sawyer, ride a raft with ol Huck Finn.
Take a nap like Rip Van Winkle, daze dreamin again.


Owen was singing it today and sang the part about the "cajun hideaway". Then he said "I wonder what is in that cage?". Hilarious. How do I explain cajun??
