Mrs LD ("Lara") and I will do our best to be there for 10am. It shouldn't be a problem, though we're travelling via "National Express Disgrace" from East Anglia, as we do every weekday morning. Consequently, as it's such a crap service, arrival (let alone arrival time) at Liverpool Street is variable in the extreme.
It doesn't appear they have any scheduled engineering works (or other pre-planned excuses for delays) on that weekend, so the 07:13 + a tube ride to Victoria should have us there well before 10:00.
If I don't manage to get Filmwaster shirt or other prominent item printed before then, I'll be wearing a Che Guevara T-Shirt. As I am not the smallest of people, my frame, grey crew cut and glasses should be recognisable. If someone wants to volunteer to take a note of my mobile number and give me theirs, I can also find you if we are delayed for whatever reason.
Looking forward to it....
