released the theme music to the show as their debut single on 9 June 1999. The up-tempo "Bring It All Back" reached number-one on the UK Singles Chart, and after selling more than 600,000 copies, was certified Platinum by the BPI. Commenting on the chart position of "Bring It All Back", the group felt "nervous and on-edge" before they discovered they had reached number one. Once they had received the phone call from the record company, the band celebrated the news with "cheers, shouting and crying". The group's success escalated and much like Fuller's marketing campaign for the Spice Girls, they were set to become a "marketable commodity". As evidence for this, global toy manufacturer Hasbro agreed upon an exclusive licensing agreement with 19 Management, which included worldwide rights in the fashion doll category; singing S Club 7 dolls were later released onto the market. An official magazine, fan club, and accompanying Miami 7 scrapbook were also launched furthering 19 Management's corporate aim. Over the course of the year, the group enjoyed more success in the charts after their second single, "S Club Party", entered the UK chart at number two and went straight to number-one in New Zealand. Their third single was a double A-side and featured the ballad "Two in a Million", co-written by Cathy Dennis, and retro-styled, up-tempo "You're My Number One". The former was the first single where O'Meara took lead vocals, setting the standard for future S Club 7 releases; the single also reached number two on the UK Singles Chart. Following the success of their television show and released singles, the group released their debut album S Club in October 1999. The album quickly rose to number two on the UK Albums Chart, and then became certified Double Platinum. The album consisted of a variety of styles including Motown and salsa tracks. Due to the increasing demand for the group with gruelling schedules including spending over thirteen weeks in America filming the first series of their show and their subsequent television specials, the members often felt that the travelling back and forth from the UK and the US was "perhaps more tiring than what we were actually going out to America to do". Paul Cattermole once commented that the speed of the schedule sometimes caused a "kind of dreamscape in your head", as the group often felt "jetlagged and tired". On top of the
