"Tinker, Tailor, Soldier, Spy" is a 1979 BBC television miniseries. This must be one of the best handful of series ever produced for television, as is the companion piece, "Smiley's People". Both series are based on the great books by John le Carre. Both star Alec Guiness as George Smiley; his performances are masterly. All the cast members in both productions are great. Both series are great.
This video shows the end credits for "Tinker, Tailor." The music was composed and conducted by Geoffrey Burgon. The title of the end credits music is "Nunc Dimittis" according to information found on Amazon.com.
N.B. The clouds are moving; the credits are running in front of a filmed scene not a picture.
N.B. 2 -- I am a fool; I just found out (8 months after posting the video) that this is being sung in English. I had assumed it was Latin and hadn't really bothered listening to the words. Thanks to Desperate Irish Housewife, I will enjoy this beautiful music even more.
[Luke 2: 29-32]
Lord, now lettest Thou Thy servant depart in peace
According to Thy word.
For mine eyes have seen Thy salvation
Which Thou has prepared before the face of all peoples
To be a light to the Gentiles,
And to be the glory of Thy people, Israel.
Glory be to the Father,
and to the Son,
and to the Holy Ghost.
As it was in the beginning,
is now, and ever shall be,
world without end.
P.S. Thanks to EC4LS (11/2008), I can add that the singer is Paul Phoenix. Here is a statement I found: "Born on April Fools Day in 1967, I started my singing career some hours later! That seems to be my recollection - singing is something I have been doing and focusing on for as long as I can remember. I became a chorister at St. Paul's Cathedral when I was nine under Barry Rose. Life was both challenging and rewarding, and I was lucky enough to make several successful recordings, including the theme music for the TV drama, Tinker, Tailor, Soldier, Spy."
P.P.S. Here it is, 2012, and we now have a movie of TTSS (I haven't seen it yet but plan to--the reviews are good). I have edited the title of this posting in order to make it easier for people to avoid this if they are looking for something from the movie.
