I made this arrangement as a teenager and played it at church shortly before serving as a missionary.  I wanted it to evoke feelings of childlike enthusiasm coupled with exciting adventure, which is how I felt about serving a mission.  

This is a slightly different arrangement from the piano solo version.  This version uses the song, "We'll Bring the World His Truth", instead of "I Want to Be a Missionary Now".  

This is the cello part for the piano/cello duet listed above.
