Click on either the little "dialup" or "broadband" buttons on the NY1 page about the Tonys to see a short clip from The Real Thing, as well as a shot of Ms Ehle embracing her mum and thanking her parents in her speech. Her bit starts about 52 seconds in.
[edit: apologies, intelligence malfunction. Copied the wrong link by mistake. The video from the awards ceremony is here]
NY1 also has an article about the Tony nominations, but the videos don't work for me. You can try your luck.
