"Wedding Song (There Is Love)" is a title of a 1971 hit single by Paul Stookey: the song—which Stookey credits to divine inspiration—[has since been recorded by many singers (with versions by Petula Clark and Mary MacGregor returning it to the Billboard Hot 100)—and remains a popular choice for performance at weddings.

Petula Clark recorded "Wedding Song (There Is Love)" in the August 1972 sessions at Trident Recording Studios in London for her album Now produced by Mike Curb with the album's arranger Don Costa. "Wedding Song..." was issued in September 1972 as the second advance single from the Now album which would be a December 1972 release: "Wedding Song..." would chart at No. 9 on the Adult contemporary music charts and reached No. 65 on the Billboard Hot 100.

In the UK "Wedding Song (There Is Love)" had an October 6, 1972 single release, being Clark's first UK single release since "I Don't Know How to Love Him" in November 1971. "Wedding Song..." did not enter the UK singles chart despite being aired on October 26, 1972 Top of the Pops broadcast.

A minor mainstream Pop chart item in Canada with a No. 67 peak, "Wedding Song (There Is Love)" afforded Clark a major hit in Australia in the spring of 1973, spending 11 weeks in the Top 20 with a peak of No. 10. Clark also recorded a French rendering of "Wedding Song (There Is Love)" entitled "Il est temps", featuring lyrics by Pierre Delanoë: this version was issued as the B-side of Clark's December 1972 French single release "Bleu, Blanc, Rouge" and was included on Clark's 1973 francophone album Petula.

The 2002 DVD release Petula Clark: A Sign of the Times which features footage from Clark's performance at the Virginia Arts Festival May 20–21, 2001, includes her performance of "The Wedding Song (There Is Love)" (so entitled).
