This one here is the theme they did for a VD film called Damaged Goods (IMDB), the only feature film by king of the high school scare film, Sid Davis.

They also had a feature film in the 1960s (made in Japan),Beloved Invaders (IMDB) that is on a region free, NTSC DVD in Japan.
More recently, when I saw them for the second time with the son of Mel Taylor on drums, they were pathetic fuddy daddies, barely able to remember the chords. (I recall a review of their re-recorded "hits" a few years back, that said they sounded like a high school band trying to imitate the Ventures.) They toured Japan forever, six monthe a year, Don Wilson told me, and put out a whole buncha albums there never released here.
Also, Nokie Edwards appeared with them in the U.S. where they rarely played in recent years, but in Japan he was a solo artist, and the lead was played by Gerry McGhee.
