Great to hear! My friend saw the show Friday and felt some of the high/falsetto notes were restrained (compared to when she saw the show a few months ago.)
I saw him Wednesday night and while his falsetto voice was a bit weaker (particularly at the beginning, it got stronger as the night went on), his regular singing voice was sensational as usual.
The last time I saw the show, I thought Ben's voice was a little scratchy in the beginning and then out of nowhere his voice came back in full force. That boy is a unicorn.
