VIDEO: Caleb Johnson performs with KISS on American Idol 2014 Finale

Caleb Johnson performed with his brother's idols KISS on the American Idol 2014 Finale.

The sang 'Love Gun' and 'Shout It Out Loud'.

Idol judges Harry Connick Jr. and Keith Urban were having a merry old time watching the performance.

This would have been better if Caleb was also in makeup, but his brother went on stage with KISS makeup on his behalf.

What a show!

Caleb can front KISS easily or any of the old school rock bands. He already has a built-in fanbase from Idol! Go Caleb! LONG LIVE KISS!!!
