I will be in Costa Rica on a mission trip in August. Every time we go there is a singalong led by one of the women there. She sings beautiful authentic Costa Rican folk songs.
If I get a chance, what song should I play? FYI the guitar available is a nylon string acoustic.
“Closer” by Nine Inch Nails
I don’t know nothing from songs, but if you’re in Costa Rica, you must buy Lizano sauce.
You won’t regret it.
Mission trip? Any real old gospel is likely to work. Many have a Spanish version. Just check with one of the locals before the singalong starts.
I must have encountered at least half a dozen Spanish and Catalan lyrics to “When the Saints go marching in,” most of which were even on print and adequate for a church environment 
What do you think of Three Little Birds? Think I can do it in spanish?
Moved from IMHO to CS.
