The ninth summer season of Barbican Sunday concerts devoted to "lost musicals" will feature the Irving Berlin/Moss Hart Face the Music; Fain and Harburg's Flahooley; the Gershwins' Oh, Kay!; and a special full-orchestral staging for one performance on September 20 of the Cole Porter/Moss Hart Jubilee, now known, of course, as the "Princess Diana" musical because she is one of the leading characters in an amazingly prescient book about royalty in crisis written only 60 or so years ago. -- By Sheridan Morley
