duet

In one clip from “The Mike Douglas Show,” the siblings perform “Chopsticks” as a screechy violin duet.

That first ovation came after Coalhouse and Sarah pledge their love and sing of a horizon of happiness in the soaring duet “Wheels of a Dream”—a beautiful highlight of a score overflowing with them.

But his design for the minimally articulated closing duet with Ms. Mearns and Stanley makes them seem to be missing lower limbs—which is just puzzling.

The arias and duets, which are almost always slowly paced and formless, lack that visceral, theatrical punch and do not musically distinguish one character from another.

The appealing title track, a duet with Sabrina Carpenter, one of many young pop stars who grew up on the older singer’s music, closes the set.
