Only two singers stand between Louisiana's finalist John Foster and the "American Idol" title. The finale will air live from 7 p.m. to 10 p.m. Sunday on ABC. Viewers determine the winner by voting, which is free. Each person can vote up to 30 times — only while the show is airing, typically until the final commercial break.

Louisiana country singer John Foster finished runner-up in the talent competition series "American Idol" Sunday night.

Louisiana's "American Idol" finalist will be performing at this weekend at the three-day music celebration in Denham Springs.
