Something not fully appreciated in the world of entertainment, commerce, and public affairs is the role of 'shadow contributors'… those who contribute their talent and expertise in the background, often unknown to the general public or consumer.
In the field of pop music, for example, the musicians performing on your favorite album are sometimes studio musicians—a skilled elite of musical specialists—substituting for the regular band members who appear in concert.
In the business world those stirring rags-to-riches autobiographies by renowned corporate leaders are often written in large part by ghostwriters, dramatizing or embroidering the historical facts.
And of course those mellifluous speeches by heads of state or political candidates are usually penned by professional speechwriters, with general direction provided by the leaders and their staffs.
But this seems to be a happy trade-off. Shadow contributors receive a respectable wage in exchange for relative anonymity.
