Apparently Alan joined a lunch on behalf of Rada in the Dorchester Hotel, October 25th of this year.
Pictures are available over here, starting with page 6.
Huge thanks to hikity_2001 for pointing us in this direction and to "ME" from the AR Downloadhaven for finding the gorgeous pictures.
obsessive sidenote: notice Alan drinks white wine and then switches over to red during lunch. *snort*
