The David Tennant Treat 4 Today has been suggested by Kerstin and this is her story from a few weeks ago:
I was visiting London (the main purpose of the visit naturally being to see the play) and happened to be "stalking" the Wyndham's stage door before and during the signing run after the MAAN matinee performance on Saturday 27th August.
I was surprised and delighted to suddenly have Mr. Bernard Cribbins stand beside me. Mr. Cribbins walked up to the crowd and called to Catherine and David (who apparently had no idea he was going to show up).
He walked up and tried to get through the throng of people (I don't think the people on the other side of the line around the barrier even knew he was there, it was pretty wild that afternoon) but had to go around to the other side because of the bars.
He kept trying to push through the crowd and attract Catherine's and David's attention, and finally (with the help of some fans calling out to them and pointing to Mr. Cribbins, as well), Catherine saw him after a few seconds and came back over (both of the had already moved down the line almost halfway).
When she recognised him, she called David back over, and they exchanged a couple of words until Mr. Cribbins walked back and around the barrier to where usher Steve then ushered him into the building, I suppose.
I took a couple more screen caps from the video of CT and DT's reactions. They were so surprised, and David started pacing, grinning like the cat that got the canary!
Many thanks to Kerstin for this story and for providing these photos. (As usual, click on the graphics for a larger version.)
