From a press release, word that you American Idol dreamers have two chances at glory at the
ballpark on Sunday: "Washington Nationals fans will have the opportunity to audition to sing the 'The Star-Spangled Banner' at a 2008 Washington Nationals game. Fans interested in participating in the auditions must e-mail
anthem@nationals.com. The first one hundred fans to sign up are guaranteed a spot in the auditions; walk-ins will not be accepted. Contestants will be asked to sing the National Anthem in under 90 seconds, the length of the anthem during pre-game ceremonies. Fans selected to perform the anthem at a Nationals game will be notified throughout the season."
Following those auditions, "the Nationals will host tryouts for one 'Take Me Out to the Ballgame' performer as part of MLB's 100th anniversary celebration of the song. Five finalists will be chosen from these auditions and one winner will be selected to perform 'Baseball's National Anthem' during the Seventh Inning Stretch at the Nationals game on May 19th vs. the Philadelphia Phillies. The final winner will be chosen through a fan vote at a later date. [...] To participate in this competition fans must RSVP at
entertainment@nationals.com."
The auditions are Sunday (April 6), with the anthems starting at noon and the 'Ballgame' singers starting at 4:00. Alas, the events are not open to the public. But if you're close by, you might get to hear anyway.
