Celebrities writing books of advice on how to have a career like theirs -- existed long before the Kardashians or Paris Hilton!
How to Become a Successful Singer is a short book of advice by Madame Clara Butt, Madame Melba, Enrico Caruso and Ben Davies, each of whom contribute a chapter. Each chapter stands alone and could be a good entry for a Short Nonfiction collection, and the whole book would be a very quick solo or group project!
