"An Old Fashioned Love Song" is a 1971 song written by Paul Williams and performed by the American pop-rock band Three Dog Night. Chuck Negron performed the lead vocal on this track. Taken as the first single from their 1971 album, Harmony, the song peaked at number 4 on the Billboard Hot 100 chart in December 1971, becoming the band's seventh top-ten hit. It was Three Dog Night's first record to top the U.S. easy listening chart. It reached number 2 in Canada. Its lyrics suggest the straightforward and melodic nature of the tune: Just an old fashioned love song / Comin' down in three part harmony / Just an old fashioned love song / One I'm sure they wrote for you and me.
