Donna Vivino (Hairspray, Wicked, Saturday Night Fever) joined host Seth Rudetsky in studio for the latest installment of OBSESSED! The two reminisced about their time in Les Miz (Vivino was the original Young Cosette, Seth was featured on "keyboard two") and Vivino broke into song with a Young Cosette/Elphaba mashup. She then channeled Fran Drescher in a tune by Amanda Green from Stars of David, a song cycle celebrating the lives of some of the world's most famous Jewish public figures.
