An Illinois man who made it to the Top 20 on last season's "American Idol" is one of two finalists on Korea's TV talent show "Superstar K."

The Chicago Sun-Times said John Park is a Northbrook native and member of Purple Haze, a Northwestern University a capella group.

Park is competing against singer Heo Gak, who told a Korean music fan Web site he envies Park's "soft smile and his flawless English pronunciation," the Sun-Times said.
