I've seen Flower Drum Song twice -- on Broadway and in Dallas -- and the cast never ceases to amaze me. They're consistently great. While no one beats Lea Salonga's performance as Mei-Li (her voice and presence alone are enough to enthrall and hold the audience), understudy Yuka Takara (who's doing the tour) proves she can do justice to the role (particularly impressive in the dance movements) and can command the stage. Male lead Jose Llana is another bright spot in this musical, delivering a powerful and memorable perforemance as Ta.
I'm not suprised that the show and the cast have been abundantly showered with praises fom critics from all the cities it has performed in (from its opening in Los Angeles to its tour in Sacramento), and that it has received accolades and nominations from at least seven award-giving bodies, with performances even videotaped for the archives of the Lincoln Center Library for the Performing Arts!
The cast recording is outstanding performance-wise and production-wise, so I'm also not surprised that it was one of the strongest contenders for Musical Cast Album of the Year in the recent Grammys (it really was the best -- Flower Drum Song's ensemble alone beats any show's ensemble for that year -- but of course, as expected, the award had to go to the good-but-overrated show with the legendary star).
Watch out for the touring production and definitely get a copy of the impressive recording!
