I, too, love Flower Drum Song, which I saw with my mother at Middletown's Paramount Theater. To this day I have no idea why she was excited to see it, since she seemed apathetic about movie going. After seeing it, I read the original novel, although I now remember little about it. The vocal score was one of the first scores I purchased in high school, and I played the music for the bridal procession to death.
I've never minded Russell Bennett's work on the show, and I think the only Broadway show he truly bombed out on was Bells Are Ringing. On the other hand, Edward Powell's film orchestrations are really wonderful and match the film's bright colors and pizazz.
