We're having an acoustic guitar for our ceremony (no lyrics, just the guitar). I've already decided on Canon in D for my processional, and I have a couple of possibilities for the signing of the registry (possible choices include I Can't Help Falling in Love with You or else Hallelujah by Leonard Cohen). But I am STUCK on my recessional song. Any ideas for something slightly upbeat that translates well to acoustic guitar without lyrics? Help me please!
