Hmmm...an interesting question. What I like about that musical (and I have the original recording) is the great Georgia Brown singing “As Long as He Needs Me.”
I only saw one production of that in London in the 1970s and it was very limp-wristed.
It has as many great songs as any American musical and its’ success here probably paved the way for the popularity of the Beatles. ‘Jesus Christ Superstar’ and Evita work better as concept albums than stage musicals.
