Lee,
How RIGHT you are! :)
Given today's technology, songs to "cover" scene changs are no longer necessary, but they used to be quite common:
"Pavane Dance" in KISS ME, KATE
"Hello, Young Lovers" reprise in THE KING AND I
"On The Street Where You Live" in MY FAIR LADY (so Eliza had enough time to change out of cumbersome Ascot gown to even more cumbersome Ball gown for Ball Scene that closed Act I!) :)
"I say YOU'RE the CUTEST one. No, I say YOU'RE the CUTEST One. And we go on like that from dawn to three."
