Gregson lists arrangements by date:

April 5, a meeting with Anna Kallin after recording "The Next Step in International Relations".
April 8, Gordon Mosley will host a dinner at the Oriental Club for BR, Charles Webster, and possibly Ivone Kirkpatrick. The recording is on BR's thesis from April 5 and will follow the dinner.
April 9, Marghanita Laski will discuss with BR the "place that women do or should occupy in our society". A dinner at the Oriental Club again precedes the recording. Gregson has also invited Edith Sitwell, but she may not be in London. Gregson mentions that Sullivan of the German Service has received BR's letter and is trying to arrange a recording session. Gregson has sent her a copy of the script to be translated.
