After, Foster took the stage to perform six songs for a large crowd of eager listeners — many of which he covered on the show. First, he sang "Don’t Rock the Jukebox" by Alan Jackson, followed quickly by Elvis classic “Jailhouse Rock."

Louisiana singer John Foster is one step closer to becoming the next "American Idol," moving into the top 7 after Monday night's vote. For "Judges' Choice" night, each finalist picked from three songs the judges had chosen for them to perform.

John Foster, a biology major at Louisiana State University, is one of five 'American Idol' contestants left vying for the season 23 crown.

American Idol season 23 returned on May 6, 2025, with the Judges’ Song Contest and the announcement of the Top 7 finalists.
