The song was covered in an up-tempo version, with slightly altered lyrics and melody, the following year by the California pop quintet We Five. Their recording reached #3 on the Billboard Hot 100 chart in September 1965 and topped the Billboardeasy listening chart for five weeks. The performance by We Five is noteworthy for the gradual buildup in intensity, starting off somewhat flowing and gentle, increasing in intensity in the third stanza and remaining so through the fourth stanza. The fifth and final stanza starts off gently and concludes very intensely, ending with a series of guitar chords.
In the United Kingdom Crispian St. Peters scored a number two hit with the song in 1966. This version was also released in the United States in 1967 and went to #36 on the Billboard Hot 100.
