I have vivid memories of watching this show as an 8 year old on our new colour TV and being fascinated by Ed Stewart's co presenter, the robot Zed. It was sort of a follow on from the earlier series Zokko. Ed Stewart has some caustic banter with his metal friend whilst film clips and animations are shown weekly - capped off with a musical guest popular or upcoming at the time including Hot Chocolate, Vanity Fare, Herman's Hermits and Mud whilst trendy young kids strut their stuff on the stage - Some hilarious scenes there. It uses Ed's radio show theme in the intro over a pre filmed backgroud. Amazingly most of the 9 shows survive in the archives in glorious PAL colour video (I believe 7 of the 9 originally made. Great fun for aficionados of 70's pop.
