at the time, using only two microphones for the five singers. Davis' solo during "Let the Sunshine In" was improvised during the session; songwriter Jimmy Webb, who happened into the studio during the recording, remarked to Howe, "My God, that's a number one record." Among the counterpoint phrases sung by Davis are: "Oh, let it shine", "Open up your heart", "You got to feel it" and "I want you to sing along with the 5th Dimension". This song was one of the most popular songs of 1969 worldwide, and in the United States it reached the number one position on both the Billboard Hot 100 (for six weeks in April and May) and the Billboard Easy Listening chart. It also reached the top of the sales charts in Canada and elsewhere. Billboard ranked it as the No. 2 Hot 100 single for 1969, although "Aquarius (Let the Sunshine In)" would go on to outsell the No. 1 Hot 100 single for 1969, "Sugar Sugar" by The Archies, and consistently ranks several positions above it in the all-time chart. The recording won both the Grammy Award for Record of the Year and Best Pop Vocal Performance by a Group for the Grammy Awards of 1970, after being published on the album The Age of Aquarius by the 5th Dimension, and also being released as a seven-inch vinyl single record. The lyrics of this song were based on the astrological belief that the world would soon be entering the "Age of Aquarius", an age of love, light, and humanity, unlike the current "Age of Pisces". The exact circumstances for the change are "When the moon is in the seventh house, and Jupiter aligns with Mars." This change was presumed to occur at the end of the 20th century; however, astrologers differ widely as to precisely when. Astrologer Neil Spencer denounced the lyrics as "astrological gibberish", noting that Jupiter forms an astrological aspect with Mars several times a year and the moon is in the 7th House for two hours every day. These lines are considered by many to be merely poetic license, though some people take them literally. The American Film Institute's 100 Years...100 Songs list, published in 2004, ranked "Medley: Aquarius/Let the Sunshine In (The Flesh Failures)" as number 33. Track listing A.
