STAGE

Former soft-porn film actress Koo Stark--once romantically linked with Britain’s Duke of York (a.k.a. Prince Andrew)--made her stage debut in London’s West End, only to be royally panned by London critics in Tuesday’s newspapers. Stark, 32, had a highly publicized 18-month romance with Andrew in 1982 and 1983--earning him the tabloid sobriquet of “Randy Andy.” He later married Sarah Ferguson. Stark, appearing in Agatha Christie’s “And Then There Were None,” disappointed theater critics. “Koo, a dab hand at thrills in her film stripping days, did a terrible job providing them with her clothes on,” wrote the unnamed reviewer for the Daily Mirror. “The evening ended up as a joke.”
