It's So Hard to Say Goodbye to Yesterday

"It's So Hard to Say Goodbye to Yesterday" is an R&B song written by Motown husband-and-wife songwriting team Freddie Perren and Christine Yarian for the 1975 film Cooley High. In the film, the song is performed by Motown artist G.C. Cameron, whose rendition peaked at number 38 on the Billboard R&B singles chart that same year. Perren also composed the instrumental score for Cooley High, and the B-side to "It's So Hard to Say Goodbye to Yesterday" features two of his score compositions from the film.

Boyz II Men cover
The contemporary R&B Motown group Boyz II Men recorded the song in an a cappella rendition 16 years later. Released as a single, Boyz II Men's recording peaked at number two on the Billboard Hot 100 and reached number one on the Hot R&B Singles chart in December 1991. The track was included on Boyz II Men's first album, Cooleyhighharmony, its name a reference to the film from which the song originated.

The music video for the song is dedicated to rapper MC Trouble, who died a few months after the album's release, and it featured archive footage of Jim Henson, Sammy Davis Jr. and Gilda Radner, and several others who had died recently.

The song was used in the 1992 action film Lethal Weapon 3, in the funeral scene for Daryl, a 15-year-old gangbanger shot down by Murtaugh.
