Tune In Rock Out
Puzzle and Song: Dan Katz
Sound Engineering: Ray Jones

The song described in the conversation can be found on LAMP, MIT's Library
Access Music Project, which allows you to search for CDs in a database and
play them over selected channels on MIT cable. The album is "My Socrates
Note" by Setec and the Astronomers, which has only one track, "The Riddle,"
which has the following lyrics:

My first is not in outer but it is in hour
My second's in devoid but it's not in devour
My third's not in philtre but it is in trifle
My fourth's not in falter but it is in rifle
My last's not in helcopter but it is in corps
Together we made music back in 1954

Now go ahead and solve the riddle you've heard
And when you're done call in the answer word
Now go ahead and solve the riddle you've heard
And when you're done call in the answer word

Of course, some of these words are not spelled as you might expect
when hearing them, but the other spellings yield no possiblities for
letters (for example, no letter is in trifle but not in filter.) Once
you have the correct spellings, the answer is clearly HI-FIS.
