Christopher’s songs were meant for you to sing–by yourself or with your faith community. There are a couple of different ways you can purchase sheet music.
The Convergence Music Project is gradually adding more and more of Christopher’s songs. This site will also have bundles, where you can get videos, audio recordings, sheet music, Power Point files, guitar charts, and more.
Fastspring.com currently has the largest selection of Christopher’s newer and older pieces. Sheet music only.
The following songs are owned by the United Church of Christ. Sheet music for these songs is sold at pilgrimpress.com. (Search for “grundy” and look in the sub-menus of each of the four pages corresponding to the sections of the “Sing! Prayer and Praise” songbook.)
