Released nine days ahead of their 1972 Summer Breeze album, Seals and Crofts' original version reached No.

Bruce Eder of AllMusic referred to it as "one of those relentlessly appealing 1970s harmony-rock anthems ... appropriately ubiquitous on the radio and in the memory".

[4] Seals and Crofts performed the song live on the Bobby Darin Amusement Company variety show in 1972.

It was sampled in the track "All in My Mind" by MC Hammer along with his newly formed rap group, Oakland Fight Club featuring Mistah F.A.B.

[20][21] Type O Negative released a cover of the song in August 1993 on their album Bloody Kisses altering their version to match their gothic metal style.

In 1998, Mexican singer Yuri recorded a Spanish language version of the track titled "Soy Feliz" ("I Am Happy") for her album Huellas.
