There were two pig puppets, a male and female and she wore a pig nose onstage with them. Early in the movie they disband their group and she tries to venture on a solo career. She ends up working for this lizard-type puppet and he's promoting another singer (he was kind of punk) who has a record called "Because I Said So". He tries to make the female character like this singer but she quits, prompting the punk guy to quit and tell him he's going back to using his real name, which was something like Melvin Sweetwater. At the end she meets back up with the two pigs. I haven't seen this in a very long time so my memory might be wrong.
