I tend to agree with Joe Offer; I mean,that shot of the submarine on the surface,leaving UK waters,with the main theme from "Ice Station Zebra" playing is iconic !!And Richard Rodgers' music from "Victory at Sea "--what can I say ?? But,sadly,many TV programmes in Britain suffer from having just the one piece of theme music,which they insist on playing at seemingly EVERY opportunity ; a good example is "Coast"---when it first came to our screens, I found the music quite pleasant, stirring,even, but now I find it repulsive and intrusive--too much of a good thing ,too often !!
