Yes, thanks.  Seems that the tr statement gets ignored altogether, but I
still don't know why.  Here it is again...

locate *.{mp3,MP3} | xargs -p -I % mv % `echo %|tr A-Z a-z`

What gets delivered back is:

locate *.{mp3,MP3} | xargs -p -I % mv % `echo %|tr A-Z a-z`
mv /home/dsj/Music/5th_Dimension--Wedding_Bell_Blues.mp3
/home/dsj/Music/5th_Dimension--Wedding_Bell_Blues.mp3?...

So, as you can see, the target filename doesn't get lowercased.  (Yes, I
see the problem with changing case in the pathname...)

Any ideas on why tr doesn't translate uppercase to lowercase here?

You can't have everything.  Where would you put it?
