"One Fine Day" was written by Goffin and King, originally intended for Little Eva. When that did not work out, it was recorded by The Chiffons, charting at number five in 1963. Carole King herself later recorded it as a solo artist, and it charted at number twelve in 1980.

I love the Reina del Cid version the most. What a beautiful song it is!
