(Significantly, the LP did not display a picture of the group on the cover, opting instead for an illustrated image of a miniature, silver-suited woman dancing on the palm of shadowed man.) It was Polci who took the lead on 'December, 1963 (Oh, What a Night),' a song that neatly straddled an evocation of the Four Seasons' past with their dance-styled present and which, when released as a single, gave them their first number one hit since 1964. It also found Valli backing off of his usual lead singing duties, often in favor of the smooth tenor of drummer Gerry Polci. Naturally, this Who Loves You album quickly followed, and it found Gaudio, who had long been the Four Seasons' Svengali as singer, songwriter, keyboardist, and producer (but who had long since retired from their stage act), composing all the music and co-writing the lyrics with his wife, Judy Parker. As a single, it peaked at number three in the Billboard Hot 100 in November 1975, the group's best showing in ten years. Noting the success of the Bee Gees' 'Jive Talkin',' a disco-oriented hit that most listeners did not recognize at first as a Bee Gees track, Gaudio fashioned 'Who Loves You,' set to a disco beat and emphasizing a harmonized chorus over Valli's solo singing, its title borrowed from the popular catch phrase 'Who loves ya, baby?,' frequently spoken by actor Telly Savalas on his hit TV series, Kojak. The band had not charted since 1970 and had not released a record since 1973. After mounting a comeback as a solo artist with the hits 'My Eyes Adored You' and 'Swearin' to God' in 1974-1975, Frankie Valli, along with longtime partner Bob Gaudio, turned to their group, the Four Seasons, to work the same magic.
