With its devotion to producing American musicals the way their writers and composers intended — full orchestra, full dance numbers, big chorus and big voices — Steven Jones' Lyric Stage in Irving is starting to get the national attention it deserves. Composer Charles Strouse, in his 80s, came to see Lyric's versions of his shows Bye Bye Birdie and Rags (and he loved them). The Rodgers and Hammerstein estate helped with research for this year's magnificent staging of Oklahoma!, which used original orchestrations and added back several numbers usually cut for time. The lavishly produced three-hour show was directed by Dallas' Cheryl Denson, with the 40-piece pit orchestra directed by Jay Dias. Nobody's done an Oklahoma! this size for decades, including the recent revivals in London and New York. Lyric's cast was young and sexy; the singing and dancing sublime. Oh, what a beautiful evening.
