American Idol runner-up John Foster performed 'Tell That Angel I Love Her,' an emotional tribute to his late friends, during the season 23 finale

After watching the 18-year-old country music artist grow up and get his start in the parish's dives, festivals and churches, West Baton Rouge is ready to make the homecoming for season 23 "American Idol" finalist John Foster unforgettable.

One of the most touching moments during the American Idol season this year came when runner-up John Foster sang a song he wrote for a late friend named Maggie Dunn. The performance for Dunn helped solidify the judges' belief in Foster, who would go on to make the final two.
