Thanks again, Mats.

Actually, I did try it myself, and was fooled into thinking it worked by not 
reading the error messages and just looking at the pdf output.  I'd 
carelessly left the pdf open from the previous run with the \new DrumVoice 
statements in, so it wasn't changed and when I opened it again it looked 
like it had worked. :(

Ah well, we now all have a good explanation which I can use somewhere in the 
manuals.
