No you don't. Pygmalion was written in 1913, which places it reliably in the public domain, at least in the US. (As a US publisher I have had reason to know these things.) Under US copyright law, anything published prior to 1923 is in the public domain, end of story. It's a lot more complex in years after 1923, but that's not an issue in this case.
If your publisher is outside the US, you may have to research it further, but if your publisher is here, no problem.
