Harris also presented The Old Grey Whistle Test rock music show on BBC Two from 1972 until December 1979. His first appearance on the show was as chair of a debate on the Night Assemblies Bill, based on his experience as a journalist and at the invitation of producer Richard Williams. Shortly afterwards he was invited to be the main presenter. His velvety voice and quiet delivery earned him his enduring nickname. Harris later became notorious among the younger generation for distancing himself on air from Roxy Music's first performance on the show and deriding the New York Dolls as "mock rock".[In the summer of 1974, Malcolm McLaren and Vivienne Westwood included Harris ("or the Sniffing Whistler as we know him") https://www.mixcloud.com/john-grant4/playlists/interview-with-1970s-stars/
