The curtain of London’s Covent Garden will go up tonight after all. The resident chorus and management of Britain’s Royal Opera House have reached agreement on a wage contract, ending a strike that had delayed the opening of a new opera season. Announcing the new two-year pay accord that raises chorus members’ weekly salaries to $296 from $283, an opera spokesman said the company will perform Puccini’s “La Boheme” as planned. The 69-member chorus at the opera house had refused to sing without more money from directors of the Royal Opera--even though the troupe faces a 1987 deficit of $2.1 million.
