In 1980, an edited version of the 28 September 1979 concert was released on video under the title The Touring Principle '79; this has been cited as the world's first music video cassette and "special video effects" of the time were added to the recording. The songs featured on the video were "Me! I Disconnect From You", "M.E.", "We Are So Fragile", "Everyday I Die", "Conversation", "Remember I Was Vapour", "On Broadway", "Down in the Park", "My Shadow in Vain", "Are 'Friends' Electric?", and "Tracks". The concert itself was preceded on the original cassette by the promo video for "Cars". In 2009, The Touring Principle '79 was released on DVD with the same track listing and with the video effects removed (although the original video version with the effects is included as a bonus feature). The DVD does not feature the "Cars" video although it does include a 34-minute interview with Numan in 2009, recalling his memories of the original 1979 tour.
