Big Girls Don't Cry (The Four Seasons song) "Sherry," the lead in "Big Girls Don't Cry" is sung mostly in falsetto. With this song, the Four Seasons became the first rock-era act to hit the top spot on the Hot 100 with their first two chart entries (their first single, "Bermuda"/"Spanish Lace," did not appear on any "Billboard" chart in 1961). Various episodes of "Happy Days" feature this song, most notably when it is played in the jukebox at Arnold's diner. It was also used, with customized lyrics sung by the Four Seasons themselves, as the theme song to Joey Reynolds's various radio programs throughout the United States.
