(1990), starring James Whitmore and José Ferrer. In a nod to Show Boat, Warfield played a cameo role as a tugboat captain. Footage of Warfield in Show Boat has been included in several TV shows and/or films, notably That's Entertainment!. Warfield played his Show Boat role in two other productions of the musical – the 1966 Lincoln Center production, and a 1972 production in Vienna. He sang "Ol' Man River" in three different record albums of the show – the 1951 motion picture soundtrack album on MGM Records, a 1962 studio album featuring Barbara Cook and John Raitt on Columbia Masterworks, and the RCA Victor album made from the Lincoln Center production. He made an appearance on The Colgate Comedy Hour and on a program called TV Recital Hall in 1951, the same year that he made his screen debut in Show Boat. He later appeared on The Ed Sullivan Show in 1955. In 1961, he appeared as a recital soloist on an episode of the Young People's Concerts, conducted by Leonard Bernstein. In March 1984 he was the winner of a Grammy Award in the "Spoken Word" category for his outstanding narration of Aaron Copland's Lincoln Portrait, accompanied by the Eastman Philharmonia . And in the 1990s, he narrated a special jazz arrangement of music from Show Boat, on the PRI program Riverwalk Jazz. In 1999, Warfield joined baritones Robert Sims and Benjamin Matthews in a trio by the name of "Three Generations". Managed by Arthur White, this ensemble toured the United States giving full concerts of African-American spirituals and folk songs until Warfield's death in 2002. Decline and death Beginning in 1962, Warfield began to have trouble with his voice, a situation he described in his autobiography. By 1966 his voice had deepened from bass-baritone to a full-fledged bass, and he could not sing the climactic high note on Ol' Man River as easily as he had in the 1951 film version; to compensate how to sing even more expressively than he had before. By 1976, Warfield, although still making various stage and television appearances, was not singing as much as he had in the past. He served as narrator in various orchestral works, such as Aaron Copland's Lincoln Portrait, and occasionally performed sprechstimme roles in works by Arnold Schoenberg. In the summer of 1976, he reprised his role as Porgy in a Lake George Opera Festival production
