Song lyrics and possessives

Depends on circumstance. Long ago in the quiet of the world, I recall my older sister, while she was dating a guy name Bobby, becoming seriously flustered because of the Beatles song "Can't Bobby Love."

Lincolntf fretted, "People say both "Charles'" and "Charles's" are correct, but I can't stand using either." The Authority: "Elementary Rules of Usage, Rule #1: Form the possessive singular of nouns with 's. ... Thus write, Charles's friend. ... Exceptions are the possessives of ancient proper names...." Now, go read, study, memorize is Elements of Style, be wise, and sin no more.
