(FORTUNE Magazine) – Meet Cicero and his understudy, ''B'' -- cockatoos currently appearing in Boston in the comedy La Bete and due to make their Broadway debut at the Eugene O'Neill theater on January 31. The birds are each insured for $1,800 (against death, disablement, or anything else that keeps them offstage). The commission on their $500 policies goes to Marsh & McLennan, a brokerage firm. It insures 70% of Broadway's shows -- including the casts, props, and audiences -- against unscripted disasters. Examples, including off-Broadway productions: -- Tony n' Tina's Wedding (St. John's Church). The 1977 Dodge Monaco that ferries the couple from the church to the catering hall in this almost-real- life comedy is insured for $999. -- Miss Saigon (opening April 11 at the Broadway Theater). This English import has more than $5 million in property coverage, including $108,000 for a helicopter that lands and takes off via overhead wires. -- The Rothschilds (Circle in the Square Theatre). The 17th-century costumes on loan from the Museum of the City of New York are insured for $50,000. -- Other Peoples' Money (Minetta Lane Theatre). The producers, who make $30,000 a week in profits, have a policy insuring eight weeks of standing- room-only houses. - J.R.
