Hylda Baker sings the theme: the lyrics had been added to Derek Hilton's original instrumental for her 1969 Columbia Records disc "Nearest and Dearest" (DB 8644), though the film uses a different version.
The working relationship between Jimmy Jewel and Hylda Baker had deteriorated to the point where they would only communicate with each other through the medium of director John Robins.
A sequel, "Nearer and Dearer", was mulled but never made.
The film reworks elements from various episodes of the Granada TV series: It Comes to Us All (1968), Take a Letter (1968), Lead Me to the Altar (1968), Wish You Were Here (1969), and The Birds and the Bees (1969).
