Wanted: a font that contains music accidentals such as sharp, flat and natural

I'm creating a document about music that contains musical examples. The examples are created using mup, a program for typesetting music, where each example is turned into .eps file. The document proper is a lout file that includes the musical examples and I want to be able to refer to flat (b), sharp (#) and natural.

Does anyone know of a suitable font for gaining access to such characters from within lout?
