	   Some comments:
	   Strictly speaking, the song is not part of the article; it was
	   appended afterwards.  The composer and lyricist is Guy
	   L. Steele, Jr.
	   The melody has a certain haunting quality that is quite hard to
	   convey in ASCII text.  I don't know whether it has ever been
	   played.
	   The composer has email, so it shouldn't be too hard to find out.
Song     : 


  There is a program called TELNET to get to another CPU.
  Control up-arrow is the escape; it's doubled to send it through,
    and "quit" is control up-arrow Q.

  A hacker once used TELNET to get to another CPU.
  He knew he could quit whenever he wanted to: all he had to do was type
    control up-arrow Q.

  Instead the hacker used TEL-NET to get to another CPU.
  He knew he could quit whenever he wanted to: all he had to do was type 
    control up-arrow [at i-th time, repeat 2^i times]
    Q.
  [repeat verse n times; the choice of n is free]

  The hacker soon got bored with this, and wanted to get back.
  He sighed, and started the exponential popping of the stack:

  The hacked flushed the TEL-NET to the most distant CPU:
  He couldn't log out until he had killed them all,
    counting up powers of two: he typed
    control up-arrow [at i-th time, repeat 2^(n-i+1) times]
    Q.
  [repeat n times]

  Whew!

  The hacker's eyes were bloodshot; his fingers, black and blue;
  He wanted to log out and and go home to bed, and sleep for a day or two.
  He typed L O G O U T ... carriage return ...

  The hacker was on a network with only twenty CPU's.
  But if he had telnetted to them all,
  he would not yet be through with typing
  control up-arrow [repeat 7 times]
  Q!
