I’m transferring a couple of LDS-related songs across from my ‘general’ music website to this one, because I think they are relevant here.

This was a piano trio I arranged for three of my 9-10 year old male students to perform in Sacrament Meeting.  They LOVED practising together, and they informed me this was their favourite Primary song.

Here are all three parts: I Hope They Call Me On A Mission Trio

And if you need the score, here it is: I Hope They Call Me On A Mission Score
