Allen Fieldhouse has also hosted several NCAA tournament regionals, an NBA exhibition game, and occasional concerts such as The Beach Boys, Elton John, James Taylor, Sonny and Cher, Leon Russell, Alice Cooper, ZZ Top, Tina Turner, Harry Belafonte, Henry Mancini, The Doobie Brothers, Kansas, and Bob Hope,[8] as well as speakers, including former President Bill Clinton in 2004,[9] Senator Robert F. Kennedy (which drew over 20,000) in March 1968,[10][11] and anarchist Abbie Hoffman in 1970.

[17] The prior record of 126.4 dB at Kentucky's Rupp Arena which lasted less than three weeks also had many Kansas fans present as the Jayhawks beat the No.

[19][20][21][22] Despite the venue being open for almost 70 years, entering the 2023-24 season, Kansas men's team has only lost 117 games at Allen Fieldhouse and only 19 under head coach Bill Self.

However, university officials were able to find a loophole: by adding some rooms for gun and weapons storage, construction of the building was able to continue under the guise of an "armory.

[24] Renovations have included minor seating expansions in 1986 and 1994, as well as accessibility upgrades in 1999 to modernize concession stands and restroom facilities, and to install an elevator in the south end.

At times the Fieldhouse has been home to men's and women's basketball, indoor track and field, volleyball, and practice facilities for the American football and softball teams.

Max Falkenstien was a stalwart figure in the radio booth, working every home game in Allen Fieldhouse from its construction to his retirement in 2006, 51 years later.

Renovations completed in 2009 include an expansion of the Booth Family Hall of Athletics and the creation of a donor atrium, as well as improved concessions, wider concourses, and restroom upgrades.

[27] On September 24, 2011, an exhibition event called "Legends of the Phog" was held, in which various Kansas Jayhawks Basketball alumni played an exhibition game during the 2011 NBA lockout, including various former players such as Darnell Valentine, Paul Pierce, Nick Collison, Julian Wright, Mario Chalmers, Brandon Rush, Cole Aldrich, Marcus Morris and Markieff Morris.

The scrimmage ended with a tie of 111-111, without an overtime, with Chalmers scoring a three-pointer in the final seconds for the white team, which was compared to his famous shot in the 2008 championship game.

In lieu of retiring numbers, banners hang on the south wall of the fieldhouse to honor former men's and women's basketball players including Wilt Chamberlain, Clyde Lovellette, Jo Jo White, Danny Manning, Paul Pierce, Lynette Woodard, Drew Gooden, Nick Collison, Kirk Hinrich, among others.

The original "Pay Heed" banner was constructed out of dormitory shower curtains by a group of KU students before a late-season game against the Duke Blue Devils in 1988 and is now on display in the Booth Family Hall of Athletics museum.

A banner reading "Just Load the Wagon" was hung on the west side of Allen Fieldhouse in 2022 to honor the father of Kansas head coach Bill Self after his passing that year.
