Have you found this technique gives useful results?

Yes -- although which parts you lose depends on how the music was
mixed, of course (and you'll quite often lose the main vocal track but
keep the stereo reverb that was added to it, for example). It's
usually most dramatic on early stereo recordings; try The Beatles'
"Birthday" for a good example, where all the instruments are in the
middle and the vocal parts are panned hard left and right...

It's also a useful technique for showing up MP3 joint-stereo
compression artefacts; a track that sounds all right in stereo will
often turn into a bubbly mess when you listen to the difference
between the two channels.
