The comedy pianist Victor Borge coined some of his signature bits on Bing Crosby's radio show during the 1940s, and later popularized them on TV on Dean Martin's show. Borge parodied classical composition styles by taking a very well known tune like "Happy Birthday to You" and playing it in the styles of Mozart, Brahms, Wagner, Beethoven and others. He would also parody two compositions simultaneously by finding common melody notes and using them for transitioning one composition into another, the most famous example being "Moonlight Sonata" transitioning into "Night and Day" (or a minor version of "Happy Birthday to You").
