"Fly, Robin, Fly" is a song by German disco group Silver Convention from their debut studio album Save Me (1975). Sylvester Levay and Stephan Prager wrote the song, and the latter produced it. "Fly, Robin, Fly" was released as the third single from Save Me in September 1975, peaking at number one on the United States Billboard Hot 100. Thanks to the success of "Fly, Robin, Fly", Silver Convention became the first German act to have a number one song on the American music charts.
"Fly, Robin, Fly" carries the distinction of being a Billboard chart-topper with only six words: the chorus simply repeats "Fly, Robin, fly" three times, with an ending of "Up, up to the sky". During a segment on VH1's 100 Greatest Dance Songs, it was revealed that the original working title was "Run, Rabbit, Run".
In April 2016, students and teachers from Methodist College, a Hong Kong secondary school, produced an educational "campus television" video by introducing four geometry methods in determining the congruence of triangles (SAS, SSS, ASA, AAS; Side-Angle-Side, Side-Side-Side, Angle-Side-Angle, Angle-Angle-Side), through a song playfully naming "RHS" (Right-angle-Hypotenuse-Side, the fifth evidence for proving congruent triangles) which lines to the tune of "Fly, Robin, Fly". Resembling the members of the band, choreographed arm and legs movements are also featured by the Hong Kong students, in order to introduce the mathematical concepts together with the lyrics ("Side angle side, side side side, angle side angle, angle angle side."). The clip has become a viral video which garnered over 800,000 views and over 50,000 "likes" on Facebook within a week, becoming one of the temporary hot topics in Hong Kong during late April, with various online parodies and social kusos provoked.
