The musical 1600 Pennsylvania Avenue, with music by Bernstein and book and lyrics by Alan Jay Lerner, was a colossal flop, premiering in May 1976, and closing after only seven performances. Most of the criticism, which told the story of the White House and commented on race relations, was leveled at Lerner's book. After Bernstein's death, a classical treatment of the music, entitled A White House Cantata, was released and is considered by many to be a forgotten Bernstein masterpiece.
