Very nice. And easy to add to my existing .ly files. This idea may also 
work for another issue I have. Different number of music pieces in the 
score. \musicA \musicB \musicC etc. In some cases only two are defined 
and in some cases five or six are defined. I should be able to used the 
defined? construct to handle that. 

Thanks.
