Recently I was listening to some pop music on the radio, which I almost
never do, and I came across a song that I realized later is quite
unique, so unique in fact that there probably aren't many others out
there like it, if any.  At least I can't think of any.  This song is
from the 70's and features a drummer but that is not what is different. 
Some of you young whipper snappers may not be able to remember that
long ago but we old timers can.  With these few clues, see if you can
figure out the song and what sets it apart.  If you have trouble I'll post more clues.
