Who Do You Think You Are?

From the introduction:

Each player takes on the role of the member of a girl group recruited by a management team. The group was incredibly successful for a short time. They appeared in numerous commercials, made public appearances, and even produced a movie that has an amazing cult following. But when one of the members decided to leave the group things no longer worked. The group produced one final album and then went their separate ways. The group is still viewed as a cultural icon and members are often asked about a potential reunion tour.
