Vaudeville star Jack Norworth was riding a subway train in New York in 1908 when he saw a sign: "Baseball today...Polo Grounds." It inspired him to write a song that became the sport's unofficial anthem.
The original recording of "Take Me Out To The Ballgame" is one of 25 such tapes that will be added to National Recordings Registry in 2011.
Another is Tammy Wynette's 1968 country hit "Stand By Your Man," which angered more than a few in the feminist movement. The song has been covered numerous times, most famously -- or infamously -- by the title characters in the 1980 film "The Blues Brothers".
Congress created the recording registry in 2000 to ensure significant audio recordings aren't lost.
