"Anything can happen in the next half hour!" There was a time when such a boast would be accompanied by a cascade of swift edits and well crafted graphics, along with a dynamic ear-worm of a theme tune to set the pulse racing. These days, when audiences have an attention span of micro-seconds, the credit sequence seems to have become a thing of the past. For me, the glory days of the credit sequence was surely the 1960s-1970s, with such shows as "The Avengers" "Department S" "Survivors" (depicting the end of the world in two minutes) and "The Sweeney". But the king of the credit sequence was surely Gerry Anderson. Not only did Thunderbirds (the proper version, not the dismal re-make) have the greatest theme tune of all time, courtesy of Barry Gray, it also had the best credit sequence, with honourable mentions to UFO, Space:1999 and Stingray ("Stand-by for action!") Any favourites you recall?
