You know, he does sound like Brokaw ... heh.
I might be sorry for askin' this, but ... who is Rochester?
This will explain who Rochester was, in a way that won't make either of us sorry.
"Edmund Lincoln Anderson (September 18, 1905 - February 28, 1977), often known as Eddie "Rochester" Anderson, was an African-American comic actor who became famous playing "Rochester van Jones" (usually known simply as "Rochester"), the valet to Jack Benny's eponymous title character on the long-running radio and television series The Jack Benny Program.
Born in Oakland, California into a family of performers, Anderson began his show business career at age 14 in a song-and-dance act with his brother Cornelius and another performer.
They billed themselves as the Three Black Aces. At a young age, Anderson permanently damaged his vocal cords (he had to yell loudly for his job selling newspapers), leading to his trademark "raspy" voice.
Benny's ordering of his "valet" and Anderson's responses (sometimes a resigned "Yes, Boss," but just as often a snappy joke at Benny's expense) were among the weekly highlights of the long-running show.
"Rochester" became virtually as popular and well-known as Jack Benny himself: his popularity was so great that some newspapers reportedly listed the Benny program as The Eddie Anderson Show."
