The Festivus Quartet: Everybody's In Charge Oboist Yuga Cohler, violinist Mann-Wen Lo, violist Christine Hung and cellist Tavi Ungerleider hail from the New England Conservatory Prep Division. The group's unusual name, The Festivus Quartet, comes from a Seinfeld reference. The quartet performs Benjamin Britten's Phantasy Quartet, Op. 2. This segment originally aired on Sept. 20, 2006.
