After the success of the M*A*S*H TV series, a long series of "M*A*S*H Goes to ______" novels appeared, beginning with M*A*S*H Goes to New Orleans in 1974. Although credited to Hooker and William E. Butterworth, they were essentially written by Butterworth alone. The sequel novels added many additional characters, mostly satiric caricatures of public figures from the 1970s: for instance, operatic tenor Luciano Pavarotti is parodied in the form of a singer named "Korsky-Rimsakov", and news anchor Dan Rather becomes the egotistical "Don Rhotten". The tone of the Butterworth novels is also markedly different from Hooker's original books, being much more broadly comical, less darkly satirical, and unrealistic.
After the conclusion of the "Butterworth" series with M*A*S*H Goes to Montreal (1977), a final "Hooker" novel was published, M*A*S*H Mania, which ignored the events and inconsistencies of the intervening novels and picked up where M*A*S*H Goes to Maine left off, depicting the original characters in middle age.
