American Idol season 4

This was the first season where guest judges were invited to participate in the auditions.

• Mark McGrath of Sugar Ray, Washington, D.C. auditions
• Gene Simmons of Kiss, New Orleans auditions
• Kenny Loggins, Las Vegas auditions
• LL Cool J, Cleveland auditions
• Brandy, San Francisco auditions

Where there were four judges present, three "yes" votes were required for the auditioner to proceed to Hollywood.

This was also the first season with the age limit being raised to 28. Among those who benefited from this new rule were Constantine Maroulis, Bo Bice, Scott Savol, and Nadia Turner.

Auditions for the fourth season began on August 4, 2004, in Cleveland, Ohio.^[1] An audition was originally planned for Anchorage, Alaska, but that was canceled due to a possible schedule conflict as a result of hurricanes affecting the Orlando auditions.^[2]

There were 193 contestants in the Hollywood rounds. They were split into two groups and performed on separate days at the Orpheum Theatre in Los Angeles. The contestants first chose from a list of twelve songs selected by the producers. They were separated into groups of males and females, but they performed solo with piano accompaniment and back-up singers. Ninety-five contestants were eliminated after this round (and one withdrew). The remaining 97 contestants competed in the second round which featured group performances. The songs for the groups were the Four Tops' "I Can't Help Myself (Sugar Pie Honey Bunch)," The Temptations' "Get Ready," Barry Manilow's "Jump Shout Boogie," The Marvelettes's "Please Mr. Postman," and The Supremes' "Where Did Our Love Go." 75 remained after this round.

In the last round, they performed a cappella. After their performances, the contestants were divided into four groups in separate rooms. Two groups were eliminated and the number of contestants was cut to 44. After further deliberation by the judges, 24 semifinalists–12 men and 12 women–were selected. At the Pasadena Civic Center, each contestant took the elevator from their holding room to the floor above to see the judges, who then revealed their fate.

The rules for this season's semifinal round were changed so as to result in an equal number of male and female finalists. Twelve men and twelve women competed separately on consecutive nights, with two from each group being voted off each week until twelve finalists were left: six men and six women.

During the season, Corey Clark, a second season contestant who was disqualified for having an undisclosed arrest record, alleged in an interview on ABC's Primetime Live that he had had an affair with Paula Abdul while on the show.^[10]

During the top 11 competition show, three of the contestants had their voting telephone numbers improperly displayed. The Wednesday night show, which was supposed to have been the elimination night, allowed viewers to vote again as the numbers were fixed, and the elimination took place on Thursday.

Bo Bice was revealed to have been arrested on a felony cocaine possession charge in June 2001 in Madison County, Alabama and was also arrested two years later for marijuana possession, public intoxication, and possession of drug paraphernalia.^[11] Scott Savol was also revealed to have been convicted of a misdemeanor charge of disorderly conduct for domestic violence.^[12] However, no action was taken against either contestant by the show producers because they had revealed their misdemeanors to them in advance.^[13]

Its Tuesday episodes averaged 27.32 million (ranked first) while the Wednesday episodes averaged 26.07 million (ranked third).^[14] It also propelled Fox, for the first time ever, to become the top network in the 18-to-49 demographic for the season.^[15][16]

Note 1: The Top 11 Wednesday night was a repeat performance night due to a mix-up in the phone numbers for the contestants. The result show was moved to Thursday.
