Before I go insane I need to find out the name of a film I used to watch as a kid. 80's early 90's animated film, it was a fantasy feel, with the theme being about stars/space. It has a girl in it called cellist and a horse andromeda. We think the baddy is called benevolence, they have to get to a north star or dark star. It was on VHS one of those with two films on one tape. Argh I'm going mad trying to find out if anyone has any ideas please help.
