Co-host
Kevin Jewell
Kevin serves as research assistant for the show. It's basically his job to tell Jason who he should have on the show and why, since he basically knows way more about Christian Music than Jason ever could. But, he's also markedly older, so that makes sense.
Anyway, Kevin and Jason have pretty much been best friends for almost 40 years, so it's completely fine that Jason is writing Kevin's bio. In fact, Kevin will probably never even read it, so it's a perfect opportunity to state that Jason is Kevin's inspiration in life and only Kevin's own wife is held in higher esteem - except Jesus, of course.
Also, the head shot may or may not include Kevin's real hair.
