Nice one!
Living in the UK in the 60s and 70s, a lot of my earliest TV theme memories are home- or Europe-based, alonside some classic US ones.
From the UK, we have Randall And Hopkirk, Catweazle, Quiller, UFO, Space 1999 and The Prisoner, to name a few.
Europe gave us Robinson Crusoe.
The US had many more, eg. Batman, Banana Splits, Sesame Street, Tomfoolery... I could go on.
Always been a connoisseur, it takes a while for a theme to really grab me. I can't think of ONE from the last 20 years which fits the criteria of greatness I believe in...
Cool thread!
