At church this morning, the pastor in his sermon was talking about the 1963 movie Lillies of the Field, in which Sidney Poitier played a handyman who built a church for a group of East German nuns. (According to wikipedia, Poitier won a 1963 Academy Award for that role, and that was "the first time a black man won a competitive Oscar.")
The pastor mentioned a song in the movie, "Amen", which Poitier's character sings. See here.
But, actually, Poitier does not sing the song, for he was tone-deaf,
and it was sung instead by the one who wrote the song, Jester Hairston.
Hairston's singing was dubbed into the movie.
name "Jester Hairston" sounded familiar to me. I only knew of one
person who had the first name of "Jester", and it was the guy who played
the sharp-witted old man Rolly in the series Amen,
which ran from 1986-1991 and starred Sherman Hemsley. But I could not
remember the actor's last name. It turned out that the guy who played
Rolly indeed was Jester Hairston, the author of the song "Amen"! See here.
Also, see here for some YouTube Rolly scenes.
