Apparently there's a Bee Gees biopic coming out. It could feature their early days in Australia, their late 70s heyday and personal problems after that.
Howabout :
Village People - Ups and downs of the group. Could end with the You can't stop the music movie flopping BUT was a big hit here in Australia where they attend a big premiere party for it...
Bone Thugs & Harmony : messed up street kids who became hip-hop stars. One of them was "the kid on the milk carton"....
The Shaggs : (quirky indy comedy). 60's Teen girl group who made a really weird album after being pushed into it by their father. The enjoy a bizarre cult following...
and YOURS?
