Maybe I'm a little late on this but I've just stumbled upon footage of The Action on Dick Clark's "Where The Action Is" TV program that some friends have shared today on Facebook. The segment was recorded for broadcast here in the States and was filmed outside Albert Hall March 17, 1966 alongside The Small Faces, The Yardbirds, The Spencer Davis Group, Them,Unit 4 + 2, The Mindbenders, The Nashville Teens, The Moody Blues and The Zombies. Still photos of many of these acts performing for the show cropped up in Rhino's excellent pictorial "The British Invasion" (featuring a tasty live shot of five piece Action onstage at The Marquee). The clip quality is shit but still amazing to see!
The band also "recorded" "Land Of 1000 Dances" for the broadcast but that has yet to surface. "I'll Keep Holding on" was broadcast in a May episode of the show while "Land Of 1000 Dances" was shown in June.
