For background, I had tried to sing to the twins as they went to bed and been adamantly told, "No singing. Moozik on." I had left the room. Whereupon the following was heard, many times over:
D4: Mama sing! Mama sing! Mama siiinnnggg!
D3: Jesus love me, he who die . . .
D4: No, D3! Quiet! Go sleep!
D3: I singing!
D4: No, Mama sing! Mama sing! Maaammaaaa siiinnnggg!
