Harry also sang the song during an appearance on the TV show "Playboy After Dark.":
That was live. It just happens that in writing that particular thing it was really a lot of work so it stayed with me longer because it was four minutes of peoples' names and their jobs. So it was trying to write a melody to encompass the names and the jobs to make it come out rhythmically and in rhyme. You know, it was a very difficult thing so you spend a lot of time with it. And I became very familiar with the cast and crew of the movie.
