Of course the song is really called "Tiny Dancer" and it was a hit for Elton John in the early 1970's. But let's think if this in terms of requirements. What if someone specifically asked him to write a song about a Tiny Dancer, but heard "Tony Danza" because of poor listening and/or communication? What if he then went on to record that song about Tony Danza? It's not likely to have been the hit that Tiny Dancer was. In fact, Elton's career may have ended there rather than go on to sell millions of albums.
