Cellist Yo-Yo Ma and the Borromeo String Quartet helped the nation mourn Massachusetts Sen. Edward M. Kennedy, who died of brain cancer August 25. Kennedy was 77. At a private ceremony for Kennedy's family and friends on August 28, the Borromeos performed the Haydn Sunrise Quartet, Beethoven's "Andante, ma non troppo e molto cantabile," from String Quartet in C#, Op. 131, and the Adagio from Charles Ives' String Quartet, No. 1. Ma performed the Bach Cello Suite, No. 6, at the televised August 29 funeral mass at the Basilica of Our Lady of Perpetual Help in Boston, followed by a duet with tenor Plácido Domingo, who sang César Franck's Panis Angelicus. Kennedy, the youngest of four brothers in the influential family, was remembered for championing health care reform and other causes. He was eulogized by President Barack Obama and buried in Arlington National Cemetery.
