Keith Urban and the other judges from this season of 'American Idol' took to the stage for the season finale Wednesday night (May 21) to perform 'True Colors' and 'Go Your Own Way.'

They opened with 'True Colors,' which Cyndi Lauper took to No. 1 in 1986. Decked out in a nude bustier, Jennifer Lopez handled the vocals, while Harry Connick, Jr. played keys, Urban played electric guitar, and former judge and current mentor Randy Jackson held down the bass lines.

They segued into 'Go Your Own Way,' which ramped the energy up considerably as Urban stepped to the mic to sing lead. All of the judges shared harmony vocals on the track, which comes from Fleetwood Mac's classic 'Rumours' album.

Lopez' wild dancing contributed to that energy, but it was really the instrumental and vocal interplay -- topped off by Urban's jaw-dropping guitar solos -- that made the track one of the high points of the night.

Caleb Johnson was crowned this season's winner at the end of the evening.
