VIDEO: Watch a Nervous Harry Connick Jr. 'Audition' for AMERICAN IDOL

On last night's AMERICAN IDOL, when judge Jennifer Lopez stepped away briefly, her fellow judges Harry Connick Jr. and Keith Urban had some fun on their own. Watch below as a "nervous" Harry musters up the courage to perform the "Star-Spangled Banner" for Keith in his 'Idol' audition!

Also below, check out some of the highlights from last night's auditions from Detroit including:

Melanie Porras served up a double dose of performances for the judges. Check out her renditions of "Fever" by Peggy Lee and "Wanted Dead or Alive" by Bon Jovi!

It's no surprise Detroit native Ayla Stackhouse was influenced by the classic sounds of Motown. Would her spin on the Little Mix hit "Wings" impress our judges?

Honoring a request by her late father, Marrialle Sellars is determined to use her gift of performing. Watch as she performs "Grenade" by Bruno Mars for the judges!

No other show in TV HISTORY has proven to be a force in the entertainment industry like AMERICAN IDOL. American Idol solidified itself as the No. 1 television show for nine consecutive seasons and, following its 12thseason, still remains a Top 5 program. IDOL is the gold standard and the only TV singing competition show to produce hit recording artists. From the first-ever IDOL winner, Kelly Clarkson, who continues to dominate the charts with three Grammy Awards under her belt, to Season 11 winner Phillip Phillips, whose debut single, "Home," has become the best-selling single of any IDOL to date, American Idol is a bona fide cultural phenomenon. Season 12 winner Candice Glover continues to show the strength of the IDOL brand when her album, "Music Speaks," was the first album from an IDOL to debut in the Top 5 on iTunes when it was issued for pre-order on the night of the series' season finale.

IDOL's impact on the entertainment industry resonates beyond the scope of television. The series has brought generations together with a common goal: to discover the next music superstar. Over the past 12 seasons, IDOL finalists have released more than 200 albums, scored 400 No.1 Billboard hits, garnered more than 250 million iTunes downloads and have been certified with 95 gold and 83 platinum records. IDOL contestants have conquered Broadway, television and film and have won numerous awards and accolades, including American Country Music Awards, Country Music Awards, Grammy Awards and an Academy Award.
