Both Shepherd and Willis sang musical numbers over the course of the show. In "The Dream Sequence Always Rings Twice," Shepherd performed both "Blue Moon" in Maddie's dream sequence and The Soft Winds' "I Told Ya I Love Ya, Now Get Out!" in David's, while in "Atomic Shakespeare," Willis sings The Young Rascals' "Good Lovin'". Willis also frequently broke into shorter snippets of Motown songs. "Good Lovin'," "Blue Moon", and "I Told Ya I Love Ya..." appeared on the Moonlighting Soundtrack.
