I saw (rented video), probably late 80's.  I do not believe it was newly released.
It is a story of a brother & sister (possibly?) twins.  The sister is a singer. The sister dies, I believe electrocuted in a bathtub.  The brother then assumes he identity.  this may be a French film??  I would love to see it again.  Any information that anyone could supply would be greatly appreciated.
Thanks
