I'm sorry but if you're describing what either Sally Murphy or Michael Hayden do on the cast album of Carousel as "barely sing" ... then yes, we are coming not only from different sides of the spectrum, but different experiences of reality.
But no, I'm not somehow who wants acting despite bad singing. I was great singing and great acting at the same time. Sally and Michael are able to sing very well. I think Michael isn't trained enough, perhaps, to sustain it all the time, and Sally I think can but doesn't have the power. I'm not someone who wants a Sweeney who can act it even if he can't sing it. No thanks. But I look at the entire performance. And for me, Sally and Michael nail the singing and their acting is so incredible that it *also* makes up for whatever isn't in the singing that you wish were there.
