"Sighing Softly To The River" is a song from the comic opera The Pirates of Penzance. Peter and Brian Griffin sing it in "Peter's Got Woods" after a reminder that the latter owes a favor to the former after Peter assists Brian in this performance.
Brian: Sighing softly to the river
comes the loving breeze.
Setting nature all a-quiver,
rustling through the trees.
Peter: Through the trees.
