The Top 12 (minus Bo and Carrie) sang a Beach Boys Medley, which featured the following songs: "Fun, Fun, Fun", "Barbara Anne", "In My Room", "Surfer Girl", "I Get Around" and "Good Vibrations".
Bo Bice and Carrie Underwood both sang a song from the previous night, with Bo singing "Vehicle" and Carrie singing "Angels Brought Me Here"
Bo and Carrie sang a duet. "Up Where We Belong" by Joe Crocker and Jennifer Warnes
There was a celebrity Medley in which the different contestants sang with their Idols. This is the first time celebrities have sung with the Idols. The medley included: "Bless The Broken Road" by Rascal Flatts (performed by Carrie and Rascal Flatts), "I Believe I can Fly" by R Kelly (performed by Anthony, Anwar and Kenny G), "Walk This Way" by Aerosmith (performed by Constantine, Jessica, Nadia and Kenny Wayne Shepherd), "On Broadway" by The Drifters (performed by Scott, Niko and George Benson), "With You I'm Born Again" by Billy Preston and Syreeta Wright (performed by Vonzell and Billy Preston),"Every Time I Close My Eyes" by Babyface (performed by Mikalah, Lindsey and Babyface) and "Sweet Home Alabama" by Lynrd Skynrd (performed by Bo and Lynrd Skynrd-later joined by all the rest of the performers).
Carrie performed what would be her debut single "Inside Your Heaven" after it was announced she won.
When Simon was being interviewed by Ryan there was a lot of technical issues when they tried talking to La Toya and Matt.
After Bo's solo performance Ryan announced that they would be visiting Carrie's home and then a scene from Carrie's hometown came up on the screen then switched the the AI symbol then back again.
When Ryan was talking to La Toya you could see a hand in the bottom right of the screen.
At one point it sounded like La Toya called Bo, Bo Brice.
Season 3 contestants were special correspondents in the Top 2's home states. La Toya was in Alabama (Bo) and Matt Rogers was in Oklahoma (Carrie). Simon thought that La Toya was drunk and that Matt did such a good job he should co-host with Ryan next year.
Mikalah Gordon hosted the red carpet.
Carrie Underwood was never in the bottom 3.
Bo released his first single on June 21st, 2005, which was the highest seller at Barnes and Noble. Bice's album contains the tracks: Inside Your Heaven, which was the same as Carrie Underwood's, and Vehicle.
Ryan Seacrest: And the winner of American Idol 2005 is...........CARRIE UNDERWOOD!!!!"
Carrie becomes the second Winner (and third person overall) to never appear in the Bottom 2/3.
Bo Bice becomes the first runner-up who's audition wasn't initially shown during the audition episodes, however it was shown in the Final 4 elimination episode.
Since the end of this season it has been announced by one of the producers that Carrie won every single week of voting.
Ryan announced that the winner would receive free use of a private jet. He did not mention it, but it was a one year deal only.
For the first time a person who works for the voting company (Edward Boddington) came on stage to give Ryan the envelope which had the results. Ryan opened the sealed envelope live on stage. This is done in every season now. In season 2 Clay had said he saw the envelope back stage and that is how he knew he hadn't won, this was probably a big reason behind doing it this way. Also, to prevent any advanced knowledge, neither Carrie nor Bo sang the winner's song, since in season 3 Diana had sad she figured out she lost when she sang that song 10 minutes before the results were read.
Personality and Good Day L.A. host,Steven Edwards was used in a spoof video about Simon's new found love (which, unsurprisingly turned out to be himself). It was done as a scandal/crime show, such as America's Most Wanted.
Season 4 contestant who didn't make it to Hollywood,Leandra Jackson sang the national anthem. It started off as a video then part way through she came out live and finished it. She got a standing ovation from everyone.
Friends (and former season 4 contestants) Adam and Dirk, were invited to the finale and got introduced to David Hasselhoff. Adam had said it was his wish to be with Dirk in the finale and Dirk had said he was obsessed with David Hasselhoff, so they both got their wishes.
Bo and Carrie both received Ford cars. This is the first time this happens. Every season onward the final two get Ford cars.
Ryan did not mention how many votes there were specifically but it was announced that over 500 million votes were cast throughout the season.
Throughout the entire 4th season, Kelly Clarkson never made a single appearance.
