Well, I weren't 'round here when this thread was started but I'd do a couple weepy ones, "Amazing Grace", which I do in open G tuning on a steel bodied resonator, then "Will the Circle be Unbroken" on the Martin in E with satndard tuning and then use "I'll Fly Away" as the song to play as folks file out of the church which ig done in C in standard tuning everyone in the joint can sing along...

If you only have two songs, leave out "Amazing Grace" since it is a tad threadworn...
