For most of ''The Bob & Tom Show's'' 40-year history, the cast consisted of hosts
Bob Kevoian and
Tom Griswold, sports commentator and
comic foil Chick McGee, news director
Kristi Lee, and producer Dean Metcalf. Kevoian and Griswold originally teamed up in the early 1980s at
Petoskey, Michigan station
WJML before being lured to
WFBQ "Q95" Indianapolis in 1983 to host what was initially a music-heavy morning show. Marty Bender then arrived as both Program Director and contributor. After McGee (in 1986) and Lee (in 1988) joined the show, the primary cast that listeners would know for decades simply as "Bob, Tom, Chick, and Kristi" was set. As the show became more popular and successful,
Mark Patrick, Dave Dugan, Whit Grayson, Steve Salge, and Ron Sexton joined the
Bob & Tom staff to voice dozens of recurring fictional and parody characters. Although Salge and Metcalf were active as voices of most of the show's fictional characters and callers through early 2024, their bits still air frequently on the 24/7 stream. On January 5, 1995, Chick left
The Bob & Tom Show to become co-host of a show called
Kevin & McGee at
KGB-FM in
San Diego,
California. After six months in San Diego, McGee returned on July 10, 1995, to his former job on
The Bob & Tom Show.
Dave Wilson filled in for Chick at first and then Gunner filled in for the rest of Chick's absence.
Steve Allee is the show's music director. He has co-produced more than 50
Bob & Tom albums over the past 25 years. In the early years of the show, Pat Carlini served as a fifth in-studio cast member, joining Bob, Tom, Chick, and Kristi during their second or third hour after Carlini completed her weather-casting and news anchor duties at
WTHR television's morning news program. Since the show was first syndicated in January 1995, Dave "Gunner" Gunn sometimes filled in for Bob, Tom, Chick, or Kristi when one of them was absent. Additionally, for several days in May 2016, Gunner filled in while Chick was on vacation, which was Gunner's first appearance during all-new broadcasts in years. Subsequently, Gunner occasionally joined the cast, both to "run the board" (operate the broadcast studio's main audio
mixing console, which Tom calls "master control") and to serve as an additional co-host. Gunner served as the show's host during "Best of
Bob & Tom" broadcasts when the primary cast was on vacation until the January 2017 debut of his sports-oriented morning show on sister station
WNDE. Hosting duties for "Best of" broadcasts have subsequently been handled by Christopher Geisen, formerly of
WOFX-FM in Cincinnati, and the Kerrigan & Christopher morning show at
WTUE in Dayton, Ohio, and now a member of the show's staff. On September 1, 2015, Bob and Tom were selected as inductees to the
National Radio Hall of Fame. The induction ceremony took place on November 5, 2015, at the
Museum of Broadcast Communications in downtown Chicago. During his induction speech, Bob announced his retirement effective at the end of 2015. Bob's last day on the air was December 17, 2015. He planned to spend retirement traveling with his wife, Becky. She returned to the show on July 11, 2016, resuming her traditional news and commentary role. The show later described her as both a "co-host and news director." During Kristi's absence, Carlini had re-joined
The Bob & Tom Show as news anchor (for all four hours each morning). After Kristi returned, Carlini appeared on a half-time basis for several days. On November 17, 2016, Bob and Tom were reunited during their induction into the Indiana Broadcasters Hall of Fame. On April 3, 2017, Bob made his first live on-air appearance since his retirement for the show's annual
Cincinnati Reds Opening Day broadcast. On May 26, 2017, Bob made a second appearance at the Indy 500 Carb Day show. The "master control" seat, historically occupied by Bob, had been filled after his retirement mostly by
Bob & Tom staffers who did not speak on the air until Ace Cosby joined the show in 2017 as its in-studio engineer and occasional on-air contributor. Cosby joined
Bob & Tom flagship WFBQ in 1981 as an on-air personality and helped Kristi get her first job at the station. Tom refers to him as "the legendary Ace Cosby" as an homage to Cosby's 40 years of popularity with Indianapolis-area listeners and personal relationships with numerous rock musicians. National radio syndicator
Westwood One granted a multi-year contract extension on May 1, 2018, to
The Bob & Tom Show. iHeartMedia, corporate parent of flagship WFBQ "Q95" and another 12 of the show's 100+ syndication outlets, announced a renewed agreement on December 10, 2018, to continue airing the show on those iHeartMedia stations. Westwood One signed a multi-year agreement in October 2021 to continue airing the show on numerous Cumulus Media stations. The renewal was described as a "long-term deal." On June 27, 2022, Kristi was named as a member of the Indiana Broadcast Pioneers Hall of Fame Class of 2022, and the induction ceremony took place on October 4, 2022. The Indiana Broadcasters Association named Tom a recipient of their Lifetime Achievement Award on October 3, 2022, during the association's annual meeting.
The Bob & Tom Show celebrated its 40th anniversary on the air at flagship WFBQ "Q95" on March 7, 2023. On July 21, 2023, Ron Sexton died at the age of 52. Dean Metcalf, who served as producer for 36 years, retired from the show in early 2024. Jason Hoffsetz is his successor. In April 2025, the show began to allow local affiliates to customize its broadcast with local segments and music. On April 17, 2026, Bob Kevoian died at the age of 75 after a three-year battle with stomach cancer. In a poignant yet funny conversation that aired live on WFBQ/Q95 late that same evening, Tom discussed Bob's death with Gunner. ==Health issues and recovery==
