Theme music
I was hooked on the series from the start and loved the theme music. It wasn't till much later I found out that this was written by Dmitri Shostakovich. From his Romance from The Gadfly.
I found it quite rude of the network that Shostakovich was never credited for this. The credits just stated Harry Rabinowitz (poor Harry can't help that I think, he adapted the music but -of course- is not in charge of who's on the credits).
Anyway: I placed a correction on imdb a while ago so Dmitri is credited for his talent.
