The Children's Sacrament Meeting Program is an annual presentation by the LDS Primary children in each ward. Topics and songs are assigned by the General Primary Presidency, but local leaders expand on the guidelines, and children typically write their own "talks.".
The songs selected for this year's program are sung by a children's choir and signed in ASL by an adult, who is the only figure shown.
My only complaint, which is true of every type of instruction like this, is that you have to adjust the visual example for your own left-right arms, rather than being able to copy it mirror-fashion. It gets confusing. ( )
