Asked if the show will include their white lions and tigers, Siegfried Fischbacher said it "will be the signature of Siegfried and Roy."

BOWING OUT

The curtain came down on "The Producers" show Saturday at Paris Las Vegas, but some cast members are settling in Las Vegas.

Leigh Zimmerman, who plays the ravishing Ulla, and Bill Nolte, the crazed Nazi playwright Franz Liebkind, have purchased homes here.

"The best thing about playing Las Vegas is learning there is more to Vegas than the Strip," said Zimmerman, who plans to shuttle back and forth to Los Angeles for some acting projects.

Her husband, Domenick Allen, a member of Foreigner from 1991-1993 and Liberace's opening act for years, has embraced the musical scene.
