Awards: The director, Christopher Hodson, was nominated for an Emmy for this episode.
Date: It is late September 1915 (the letter James writes at 6'48" is dated 26th).
Goof: When talking about wedding dresses, Rose tells Georgina that Daisy is "just upstairs, slipping it on", to which Georgina replies: "Tell her to come up at once." As well as being contradictory, the latter statement implies Daisy's bedroom is on a floor below Georgina's, which seems unlikely. (8'10")
Edward background: His mother, father and (maternal) grandmother are at his wedding/reception (all three are played by uncredited extras). His best man (and best pal) is Private Charlie Wallace.
The march Edward and Daisy listen to from the servants'-hall window is Holyrood written in 1912 by Kenneth Alford (aka Major Fredrick Joseph Ricketts, 1881-1945).
The song the wedding-reception guests sing at 19'49" is It's A Long Way To Tipperary, written by Jack Judge in 1912. It became one of the most popular songs of WWI.
The huge location shoot was done at Marylebone Station in London (standing in for Charing Cross).
The tune being played during the establishing shots of the station (22') is Soldiers In The Park written in 1898 by Lionel Monckton (1861-1924).
Goof: During the scenes at the station, the position of the hatpin in Daisy's hat changes.
Goof: In the railway carriage, Charlie seems to have the top button of his uniform missing (it is present during the scenes in 165 earlier) (21'18").
The band tune being played at 24'36" is Keep The Home Fires Burning composed in 1914 by Ivor Novello with words by Lena Gilbert Ford.
Goof?: At 24'45" the Martin Adams character seems to be wearing a single glove on his left hand. As he is later waving goodbye (27'48"), the glove transfers to his right hand. OK, the character could have taken a glove off and put the other on, but I rather think this is a continuity error. Additionally, he seems to be wearing a wedding band despite apparently only being Angela Barclay's boyfriend, not husband (the ring doesn't seem to be present in the morning-room scenes earlier). (Thanks to Lois A Graham for these.)
Goof: Hudson: "I am endeavouring to explain to the girl, Mrs Bridges, that her 'bit', as she puts it..." But it was Mrs Bridges who used the word "bit" and not Daisy. (38'35")
The phone number of 165 is Sloane 3082 (but see goof below).
Goof: Reader David Village writes: "I was reading about 165's phone number. You might be interested to know that London's Sloane telephone exchange didn't actually open until 1925. I wonder if they actually looked into it, or just hoped that years later some retired GPO telephone operator wouldn't spot it!"
