From the live chat with Gladys- a girl who attended the show (it was inside a temple, and there were around 70 people):

David sang FIVE songs in SPANISH in the Bible (including Oh My Father, I Believe in Christ, and I Know That My Redeemer Lives). Then came the last 2 songs… his breathing was very heavy.. The audience did not stir not even once. He doesn’t have a Chileno accent, and they said at the beginning of the event that no pictures or videos. David sang 5 songs, and he was reading them from a book (a hymnal book I guess). A piano accompanied him.

He sang almost all of the songs with eyes closed and ended them almost like a sigh. When he finished singing, the elders whisked him away but he looked like he wanted to stay.

Gladys also said that there will be another event on a Saturday in October with just Elder Archuleta and Elder Coello (that guy David took a picture with in the bus).

Thanks to JR and Abrra for the translation.
