I have to spell out the year in quoted dialogue for work. Are these correct?<br/><br/>He said, “I like the nineteen-eighty-two song ‘I Love Rock and Roll.’ ”<br/><br/>“I loved the nineteen-seventies' fashions!” Apostrophe after “seventies”?<br/><br/>Joe said, “Nineteen fifty-nine was a great year for rock and roll.”<br/><br/>She said, “My sister was born in nineteen seventy-eight, and my brother was born in nineteen-seventy.”<br/><br/>Are the hyphens correctly employed in the aforementioned examples?<br/><br/>Thank you.
