Actor-musicians Lauren Molina (Sweeney Todd, Marry Me a Little) and Nick Cearley (All Shook Up) are the duo behind The Skivvies, known for their acoustic performances of pop songs, wearing nothing but their underwear. Molina, Cearley and their guests play instruments ranging from the cello, ukulele, guitar and glockenspiel to the melodica.
