Speaking of our new friends at the Library of Congress, here's something from their National Jukebox: Billy Murray on the Victor label in 1915 singing "If War Is What Sherman Said It Was (Then Tell Me, What is Married Life?)" Their embedding feature doesn't seem to work--or maybe I'm doing it wrong, as the old Randy Newman song says--so here is the link:

The song is by lyricist Andrew B. Sterling, a Songwriters Hall of Famer whose big credit remains "Wait Till the Sun Shines, Nellie," and journeyman composer Albert Gumble. Murray was the biggest recording star of the twentieth century's first two decades, whose career faded away when the electric microphone was invented and enabled a more intimate type of singing than the full-throated loudness that the acoustic recording horn required. In his 20-year heyday, he sang the original recordings of dozens of standards, including "In My Merry Oldsmobile," "Harrigan," "K-K-K-Katy," and (as lead tenor of the American Quartet) "Oh, You Beautiful Doll."
