Scallon's debut album "All Kinds of Everything", recorded at Decca Studios in West Hampstead, London, on the weekend of 25 April 1970, was released in June and included four tracks co-written by the singer, as well as a new recording of the album's title track. Her follow-up single was issued in September, but Jerry Lordan's "I Will Follow You" failed to chart. The song that put an end to her one-hit wonder status was found on the album "Barry Ryan 3". "Who Put the Lights Out", written by Paul Ryan for his twin brother, was offered to her by their stepfather Harold Davison, the business partner of her agent Dick Katz. Her version, cut with Barry Ryan's producer Bill Landis, proved a strong comeback vehicle reaching #5 in Ireland. In the UK it became a #14 hit on 13 March 1971. There then followed three years of unsuccessful singles broken only by the Irish chart showing of "Sunday Monday Tuesday", a #4 hit in December 1973. This lack of success caused her agent to recommend she join the former head of Bell Records Dick Leahy on his new label, GTO Records.
