the Frank Loesser musical The Most Happy Fella in 1956, with Robert Weede and Jo Sullivan. By then, the Shuberts owned the Imperial again, but they operated nearly half of all legitimate theaters in New York City at the time, prompting the U.S. federal government to file an antitrust suit against the firm. As part of a settlement made in February 1956, they chose to sell their St. James Theatre, since they would have otherwise been forced to lease the Imperial or the St. James. The Imperial also hosted the 1957 musical Jamaica, starring Lena Horne and Ricardo Montalbán with a score by Harold Arlen and E. Y. Harburg, and the 1959 musical Destry Rides Again, starring Dolores Gray and Andy Griffith with a score by Harold Rome and Leonard Gershe. 1960s to 1980s The Imperial had more long runs in the 1960s. First among them was Gypsy with Merman, which transferred from the Broadway Theatre in 1960. Next was Carnival!, which opened in 1961 and starred Jerry Orbach and Anna Maria Alberghetti. Carnival! ended to make room for Lionel Bart's Oliver!, a West End musical that had its Broadway premiere at the Imperial in 1963. Oliver! ran for a year and a half, also transferring to make way for the next production: Fiddler on the Roof, which opened in 1964. Fiddler, which featured Zero Mostel with a score by Jerry Bock, Joseph Stein, and Sheldon Harnick, stayed for nearly three years before it transferred as well. This was followed in 1967 by Cabaret, which came from the Broadhurst Theatre and ran for a year and a half before transferring. John Kander and Fred Ebb next collaborated for the musical Zorba, which ran at the Imperial in 1968. In 1970, the Imperial hosted the musical Minnie's Boys, featuring Shelley Winters, and Two By Two, starring Danny Kaye. Following these were the relatively short revivals of On the Town in 1971 and Lost in the Stars in 1972. By contrast, the musical Pippin opened in 1972 with a score by Stephen Schwartz, and it ran for over four years before transferring. During that time, the Imperial hosted the 27th Tony Awards in 1973. By the late 1970s, it was becoming more expensive to produce Broadway musicals, so the Imperial saw fewer musicals. The Imperial's productions in 1977 included Eugene O'Neill's play Anna Christie, featuring Liv Ullmann; Victor Borge's play Comedy with
