On April 24, 2008, the Cubs flew an extra white flag displaying "10,000" in blue, along with the win flag, as the 10,000th win in team history was achieved on the road the previous night. Alongside the tradition of the "W" and "L" flags, the song "Go, Cubs, Go" is sung after each home win (it was also sung by visiting Cubs fans in game 7 of the 2016 World Series at Progressive Field in Cleveland, where the Cubs clinched their first championship since 1908). Also, following the 2015 addition of the park's Daktronics video screens, the large "W" in the "Wintrust" logo on the left field video screen is kept on following Cubs' wins. "Take Me Out to the Ball Game" The tradition of singing "Take Me Out to the Ball Game" at Cubs home games began when Hall of Fame announcer Harry Caray arrived in 1982 (he had sung it the preceding seven years as a broadcaster for the White Sox), and has remained a Wrigley Field staple. After Caray's death, the tradition of a guest conductor began, with former baseball players, other sports stars, actors, and other celebrities invited to sing during the Seventh Inning Stretch. Among the best-known guests have been the actor Bill Murray, former Bears coach Mike Ditka, former Cubs second baseman Ryne Sandberg, former pitcher Mike Krukow, former longtime Cubs first baseman Mark Grace, former Houston Rockets star Tracy McGrady, Chicago Blackhawks forwards Jonathan Toews and Patrick Kane, Chicago Bears quarterback Jay Cutler, comedian Jay Leno, NASCAR driver Jeff Gordon, singers Ozzy Osbourne and Eddie Vedder, former Chicago lead singer Peter Cetera, boxer and actor Mr. T, actor and lifelong Cub fan Gary Sinise, actors Tom Arnold, James Belushi, Bill Murray, WWE wrestler/Chicago native CM Punk, Vince Vaughn, actress Melissa McCarthy, and Illinois-native country music singer Brett Eldredge.

As of July 2019, organist Gary Pressy, holds the record for 2,653 consecutive games played; never having missed a day's work in 33 years. Today, most major league ballparks have replaced the traditional live organist with canned music programmed by a DJ. Pressy says: "I don't think it's a dying art, especially at Wrigley Field ... The team respects tradition." Writing on the
