But I have often gone down the YouTube rabbit hole watching every Glinda who has done it subsequently. The only one that comes close is Ashford. And only because she is not doing a Kristen Xerox. She seems to have made the role her own. It's very obvious why she herself became a star soon after."
English Glinda’s use a jolly hockey sticks RP (posh) that isn’t a northern accent you are hearing
