The monochrome 1965 clip for Bob Dylan's "Subterranean Homesick Blues" filmed by D. A. Pennebaker was featured in Pennebaker's Dylan film documentary "Dont Look Back". Eschewing any attempt to simulate performance or present a narrative, the clip shows Dylan standing in a city back alley, silently shuffling a series of large cue cards (bearing key words from the song's lyrics). Many "filmed inserts" were produced by UK artists so they could be screened on TV when the bands were not available to appear live. Pink Floyd were pioneers in producing promotional films for their songs including "", directed by Anthony Stern, "Scarecrow", "Arnold Layne" and "Interstellar Overdrive", the latter directed by Peter Whitehead, who also made several pioneering clips for The Rolling Stones between 1966 and 1968. In the UK The Kinks made one of the first "plot" promotional clips for a song. For their single "Dead End Street" (1966) a miniature comic movie was made. The BBC reportedly refused to air the clip because it was considered to be in "poor taste". The Who featured in several promotional clips in this period, beginning with their 1965 clip for "I Can't Explain". Their plot clip for "Happy Jack" (1966) shows the band acting like a gang of thieves. The promo film to "Call Me Lightning" (1968) tells a story of how drummer Keith Moon came to join the group: The other three band members are having tea inside what looks like an abandoned hangar when suddenly a "bleeding box" arrives, out of which jumps a fast-running, time lapse, Moon that the other members subsequently try to get a hold of in a sped-up slapstick chasing sequence to wind him down. In 1966, Nancy Sinatra filmed a clip for her song "These Boots Are Made for Walkin'". Roy Orbison appeared in promotional clips, such as his 1968 hit, "Walk On".
