GSU houses one of the most important collections in the world of popular music. John Herndon Mercer began writing songs at the age of fifteen and eventually became one of the foremost figures of 20th century American popular music. His catalog includes many numbers that have become American classics, and his activities as lyricist, composer, performer and businessman span a period of nearly five decades. The collection that will be digitally preserved by Osiris Studio includes all of Mercer’s commercial Capitol Records 78 rpm recording, various other commercial releases, radio transcription recordings, and many personal recordings illustrating his song writing methods.
