If one is going to write a song, or a play, or make a film drama or a documentary then do it like Tinseltown or theatreland. Ignore the facts and make sure your errors are in Spades. For example, it`s no good singing about a "disaster" when, in truth, hardly any poor souls were lost. That doesn`t get bums on seats. Make sure there are enough lives lost and people to blame. Your version will deceive but last for years. The only downside is when schools begin to use such "traditional" songs to teach history.
