Jeopardy! The Greatest of All Time tournament kicked off on Jan. 7 with contestants Ken Jennings, James Holzhauer and Brad Rutter vying for the GOAT title.

One of the games featured an “American Idols” category, with the clues given by Idol judges Luke Bryan, Lionel Richie, Katy Perry and host Ryan Seacrest. While the clues had nothing to do with American Idol, they were framed to have relevance for the special guest.

Here is the $800 clue given by Luke: “I’ve been inspired by this idol since I was 4 years old singing ‘See See Rider,’ the first song he performed on his Aloha From Hawaii TV special.”

Amazingly, Ken Jennings responded incorrectly with “Who is Don Ho?” before James Holzhauer responded correctly with “Who is Elvis [Presley]?”

In addition, Katy Perry’s $200 clue had a country-centric connection: “I will always love this country star, and in 2016 I got to present her with the Tex Ritter Film Award for her Coat of Many Colors TV movie.”

Ken Jennings responded correctly with “Who is Dolly Parton?” on his way to winning Game 1.
