Wrapping up Johnny Carson's Tonight Show 27th anniversary program was the Doxology, as sung by L.A. Dodger Orel Hershiser. Following last year's World Series, the pitching ace delighted the late night host with a sample of the songs he sang to calm himself between innings. Carson recalled that Hershiser, an outspoken Christian, caught him a bit off guard by actually singing the song on the live program, but added that he was "moved" by it. Apparently, Carson chose the taped segment to conclude his primetime television special.
