Things got very emotional this week on Entertainment Tonight, as longtime hosts John Tesh and Mary Hart reunited on the show for the first time since 1996.

John has been making the media rounds lately, spreading the word about his new book, Relentless: Unleashing a Life of Purpose, Grit, and Faith. Just last week, John called in and chatted with Nikki and I on the HOM Morning Show about it.

In the book, John tells the story about his recent battle with prostate cancer. After receiving a grave diagnosis from his doctors, John faced the cancer head on, and went on to beat it, with help from friends, family and faith.

Watch below, as the two former colleagues relive some of their favorite moments from their ten year run on the show, and listen to John go into more detail about his battle.

And don't forget to listen to Intelligence For Your Life, weeknights on 94.9 HOM!
