The Happenings were a pop music group that originated in the 1960s. The group's major hits were "See You In September" (1966), which was originally recorded by the Tempos in 1959; a cover version of the George Gershwin/Ira Gershwin song, "I Got Rhythm" (1967), updated for the group's sunshine pop musical style; and "Hare Krishna," a cover version of a song from the musical Hair (1969). The group's "See You In September" and "I Got Rhythm" were on the Billboard Hot 100 Singles charts for 14 weeks in 1966 and 13 weeks in 1967, respectively, forming musical bookends for the 1966-1967 school year, based on their Hot 100 #3 peak dates. Both disc sales exceeded one million copies, resulting in R.I.A.A. gold record awards by 1969.
