This song from David Haas’s “Table Songs” has a specific application for weddings but that doesn’t mean it can’t be used elsewhere. It is based on 1 Cor 13 and its message is needed more generally than just at weddings. The verses sound like solo vehicles to me, which is what will happen at weddings I suspect. The refrain is more singable.
