On 31 May 1998, Halliwell announced that she had left the Spice Girls due to depression and differences between the group. The first official confirmation was an announcement to the media by her solicitor on 31 May. Her action aroused controversy, her former group being due to embark on a North American tour, which they eventually completed without her. Although she had already left the group, the Spice Girls released "Viva Forever", the final music video to feature Halliwell's likeness, plus a one-off supergroup called England United for the official England FC song (Jo Whiley introduced the band saying "...plus Geri as a substitute"). After she left, the other girls co-wrote a few songs about her, which appeared on their album "Forever": "Goodbye", "Tell Me Why", and "Let Love Lead the Way". The group is among the best-selling girl groups of all time, selling over 75 million albums.
