[Carl Sigman], 91, who wrote music or words for dozens of songs, including the theme song for the 1950s television series "Robin Hood" ("Robin Hood, Robin Hood, Riding through the glen . . ."), which starred Richard Greene, died Sept. 26 at his home here. The cause of death was not reported.

Mr. Sigman wrote the words to Duke Ellington's "All Too Soon" in 1940 and "What Now My Love," for which he wrote English lyrics in 1966 for a French song written four years earlier. Herb Alpert and the Tijuana Brass, Sonny and Cher and Mitch Ryder sang his version.
