Question: The song "Tipperary" can be confused with another song that was popular during which war?

<P0-S0> "Mighty Oregon" is the fight song for the University of Oregon. <P0-S1>  It is played by the Oregon Marching Band at home football and basketball games. <P0-S2>  Director of Bands, Albert Perfect, along with journalism student DeWitt Gilbert, wrote the fight song, "The Mighty Oregon March", which was first performed on March 4, 1916. <P0-S3>  For the song's most popular section, Perfect fashioned a new melody to fit into the harmony from "It's a Long Way to Tipperary," a hit 1912 World War I march. <P0-S4>  The catchy popularity of the harmony was not lost on Perfect, a man well-educated in music theory, originally subtitled the song "The Tipperary of the West." <P0-S5>  Over the years there have been several changes to the lyrics and, today, the middle stanza is generally the only one sung and it is done so using more modern lyrics than the original. <SEP> <P1-S0> Ryan Hamilton and Jaret Reddick decided to start writing songs together after Hamilton's band, Smile Smile, opened for Reddick's band, Bowling for Soup, on a few of their tour dates. <P1-S1>  After four days of writing, the duo had written six songs, which later resulted in the formation of the band People on Vacation. <P1-S2>  The band began streaming a song titled, "Better Off Dead," on their official site in late 2010. <P1-S3>  During his eleventh Bowling for Soup podcast regarding the band's newly announced side projects, Reddick played a demo that he described as "the first People on Vacation song," titled "Rainy Day." <P1-S4>  The band has since announced they have written and recorded fifteen songs and plans to release album in Fall 2011, through Kirtland Records. <P1-S5>  The band released another song, titled "She Was the Only One," as a free download via Twitter as a "Tweet for a Track" promotion, in addition to streaming it on their official site in January 2011. <P1-S6>  The band's music video for "Better Off Dead" premiered on the Dallas Observer website on January 19, 2011. <P1-S7>  In an interview with aduioADD, Hamilton jokingly named the album "Buskin' & Name Droppin"'. <P1-S8>  Another song "Because of the Sun" was played live on 102.1 FM for the first time in March 2011. <P1-S9>  In order to promote the project, the band joined Bowling for Soup's 2011 UK Acoustic Tour as an opening act, alongside Linus of Hollywood and Erik Chandler and the Mulberry Street Socialites. <P1-S10>  In July 2011, Reddick explained the band expects "a long EP out around the end of November, with a full length album hoping to be out by next summer with all new material," stating the band has fifteen songs that are "written, recorded, done" except for drums while they have written six to eight other songs that have yet to be recorded. <P1-S11>  The band will be having its CD release show for "The Carry On EP" on November 24, 2011, at the Kessler Theater in Dallas, Texas. <P1-S12>  Reddick announced in a recent podcast that People on Vacation would be making a music video for the song "Where Do We Go," which the duo filmed with Built By Ninjas in January 2012. <SEP> <P2-S0> "It's a Long Way to Tipperary" is a British music hall song written by Jack Judge and co-credited to Henry James "Harry" Williams. <P2-S1>  It became popular among soldiers in the First World War and is remembered as a song of that war. <P2-S2>  It was allegedly written for a 5-shilling bet in Stalybridge on 30 January 1912 and performed the next night at the local music hall. <P2-S3>  Now commonly called "It's a Long Way to Tipperary", the original printed music calls it "It's a Long, Long Way to Tipperary." <SEP> <P3-S0> "Tipperary" is the name of an Irish-oriented love song written in 1907 by Leo Curley, James M. Fulton and J. Fred Helf. <P3-S1>  It is not to be confused with the much better-known song from 1912, "It's a Long Way to Tipperary". <P3-S2>  Both were sung at different times by early recording star Billy Murray.
