Rudyard Kipling's If was actually put to music in the musical Just So (which was based on RK's Just So stories), and it's on the musical's soundtrack, performed by John Barrowman.
A great poem and a great song.
Mulder: Imagine if you could come back and take out five people who had caused you to suffer. Who would they be? Scully: I only get five? Mulder: I remembered your birthday this year, didn't I, Scully?
