I was asked by my Primary President to teach "Gethsemane" to the primary children this year. And I was delighted to to find that the Church put this song out in the March 2018 Friend Magazine, so there was no worry about getting it approved or purchasing music.
I love the sing-along video that the Church put up on their website (https://www.lds.org/media-library/video/2018-03-0020-gethsemane?category=sing-along-videos&lang=eng) and I'm planning on showing it in primary to introduce the song. There were a few flipcharts online that I was able to find, but all in portrait mode. So, of course, I made my own version that is landscape mode so I can put it in my binder and hang it over my music stand.
