Ever since the Troubadours, the theme of spring and love go together in poetry/song. So here's the chorus from one the songs of the Gypsy Scholars "The Troubadours & The Beloved" musical essay series:
"So in a world of snow, / Of things that come and go, / Where what you think you know, / You can't be certain of, / You must believe in Spring and love." ('You Must Believe In Spring,' Mary Ann Moore)
Compare the Romantic poet Shelley's verse from 'Ode to the West Wind' (1819):
“O, wind, if winter comes, can spring be far behind?”
The speaker invokes the “wild West Wind” of autumn, which scatters the dead leaves and spreads seeds so that they may be nurtured by the spring, and asks that the wind, a “destroyer and preserver,” hear him. The speaker calls the wind the “dirge / Of the dying year,” and describes how it stirs up violent storms, and again implores it to hear him. The speaker says that the wind stirs the Mediterranean from “his summer dreams,” and cleaves the Atlantic into choppy chasms, making the “sapless foliage” of the ocean tremble, and asks for a third time that it hear him.Speaking both in regard to the season and in regard to the effect upon mankind that he hopes his words to have, the speaker asks: “If winter comes, can spring be far behind?”
