    channel.  That's all those "vocal eliminators" do.  They assume that
    the vocals will be in the "center" of a stereo image.  They usually
    cancel out the drums as well since drums are also usually mixed to be
    equal left and right.

In addition to the above, they usually use filtering to try to restrict
the cancellation to frequencies where vocals tend to be found.  Nonetheless,
you're still going to lose some stuff in addition to the vocals.
One of the music comics, maybe Electronic Musician, had an article on 
building your own vocal eliminator awhile back.

    Thanks for the input.  I'll just do this in my spare time, especially
    since I am s-o-o-o electronically inclined .. :-)
    
    From all input so far, a quality result is not as easy to
    get as I had hoped.  As mentionned, I will lose certain tones
    of the instrumentals along with the vocals, as they may be in
    the same frequency range.  In some cases, the record companies
    make 'Maxy-singles' of songs which have the instrumental on
    one side, and the vocal on the other.  In this case, such was
    not the case.
