Bernard J. McGuirk is the executive producer of the Imus in the Morning radio program. He was born and raised in the South Bronx, New York, where he worked in his younger years as a taxi driver.
Sid Rosenberg is a radio personality and the former morning host of WMEN-640 AM. Rosenberg is known for his controversial and sarcastic humor as a host on many radio stations including, WAXY "790 The Ticket" in Miami, where he hosted his own morning show. He originally was paired with O.J. McDuffie, formerly a wide receiver with the Miami Dolphins; McDuffie resigned his position with the station in the summer of 2006.
Rosenberg's self-given jokingly middle name "Arthur" is a reference to former baseball player Dave Kingman. When Hall of Fame sportscaster Bob Murphy gave the lineups for the New York Mets, he would always give Kingman's name as "David Arthur Kingman"; Rosenberg continues this running gag on the Sports Guys by using Arthur as everybody's middle name.
His radio career started in West Palm Beach, Florida, where he hosted the syndicated sports radio program The Drive on Sports Fan Radio Network in the late 1990s, after starting as an Internet broadcast. In 2000, he moved to New York City to co-host WNEW-FM's turbulent morning show, the Sports Guys. A year later, he joined the Imus in the Morning program. He shared the sports broadcasting duties with Warner Wolf before becoming the full-time sports reporter. He engaged in heated half-mock, half-serious disputes with the other members of the Imus cast, leading for example to an actual boxing bout with producer Bernard McGuirk. Several months after joining the Imus show, he became the co-host of the midday show on Imus' flagship station, WFAN. Here, his strong knowledge of sports and distinctive, high-pitched Brooklyn accent served him well. He would hold both broadcasting positions until 2005. For several years, he also hosted the radio pre-game shows for New York Giants home games.
