The song "When I Kissed the Teacher" is by the pop band ABBA. It was released as the opening track on their album "Arrival" on October 11, 1976. The recording sessions for the song began earlier that year on June 14, 1976. The song's lyrics tell the story of a student who has a crush on her teacher and one day kisses him. ABBA also recorded a video for the song featuring the band members as schoolchildren and Magnus Härenstam playing the teacher who gets kissed. Additionally, "When I Kissed the Teacher" was covered with a slight lyric change by Lily James and others for the soundtrack of the film "Mamma Mia! Here We Go Again," released as a single on May 8, 2018. So, the original song dates back to 1976, with the popular re-release version in 2018.
