I think it's actually a bit depressing. This show has had numerous revivals including Chichester a few years ago. It's a dated musical and it just about sums up the ambition of British musical theatre today. Sigh.
I saw it at Chichester and the most recent Broadway revival a few years back and it's actually a really dull musical. Obviously a couple of great tap numbers but the rest of it is so creaky. Unless they have mega stars lined up for this, it will really struggle.
