Radio Ga Ga is a song performed and recorded by the band Queen, written by their drummer Roger Taylor. The song was a commentary of the invention of television overtaking radio's popularity, and how one would listen to radio for their favorite comedy, drama, sci-fi programs and so on as well as the advent of the music video and MTV. Taylor originally conceived it as "Radio Ca-Ca" (apparently from something his toddler son once said), a slam against radio for the decrease in variety of programming and the type of music being played. It was eventually changed to "Radio Ga Ga", because it sounded better, clearer, and rolled off the tongue easier. David Mallet's music video for the song features scenes from the film Metropolis—Freddie Mercury's solo song "Love Kills" was used in Giorgio Moroder's restored version of the film, and in exchange Queen were granted the rights to use footage from it in their "Radio Ga Ga" video. However, Queen had to buy performance rights to the film from the communist East German government, which was the copyright holder at the time. Critics said that the video looked like a "Nuremberg Rally" much to the anti-Nazi Roger Taylor's dislike. In the video there is a part where they list some of their earlier videos in a photo album, illustrating the changes and the influence videos received through the years. In filming the "clap" sequence, the extras got the beat down perfectly; the band members, however, needed some practice before they got it right. All the extras in the "clap" sequence were recruited from the band's official fan club.
