After Robyn Loau departed "Girlfriend", Melanie, Jacqui, Lorinda and Siobhánn, changed the bands name to GF4 and continued as a quartet. The band name wasn’t the only thing that changed! The girls had grown up and adopted a more grown up, sexual image. Their first single, a cover of the song "Sooner Or Later" became a huge hit in the charts and clubs around Australia. Not only that, but the CD Single was the first ever Interactive CD Single manufactured in Australia. The CD, now primitive by today’s standards, was full of photos, video clips, and interviews with the girls.
