Dave etc.I have the sheet music of "Sucu Sucu", which was indeed the theme music from the William Franklyn TV series "Secret Agent".
Following the "scary" link above takes you to the website of a N&F tribute duo, which is indeed scary, but does have an additional link to a newly released CD of the original N&F's greatest hits. Unfortunately, it looks as though some prat has mixed it so that every other track is a Christmas Carol! Fine within the octave of Christmas, but I can see many people ripping their own CD, omitting the Carols (or, maybe, the secular stuff, according to taste and conviction).
