Chances are that a majority of our readership doesn’t watch American Idol (we prefer The Voice ourselves). However, if you did catch last night’s (February 22) episode, then you likely saw Flotsam And Jetsam singer Eric “A.K.” Knutson with his biological son on the singing competition show.

Creighton Fraker, who just made it into the show’s final 24, was adopted as baby by a preacher in South Dakota. At age 25, though, Fraker discovered that his biological father was none other than the frontman of 80’s thrash metal group Flotsam And Jetsam. Since then, the two have remained close.

In addition to airing an interview with Fraker explaining his relationship with his father, Knutson was also present at the show’s “final judgment” along with other family members to show support. Not only was it cool to see a member of Flotsam And Jetsam on American Idol, but it’s also heartwarming to see Knutson with his son.
