KING OF THE WORLD: Trump just met with a classic-rock legend and a missile-defense expert — and it was the same guy.

Jeff “Skunk” Baxter has earned eight platinum records in a music career that started in the 1960s, and he has received numerous security clearances and contracting jobs since the 1980s as a self-taught expert on missile-defense and counterterrorism.

Baxter was one of many luminaries at the White House on Thursday to watch President Donald Trump sign the Music Modernization Act, which reforms copyright laws.

Unlike every other musician in the room, including Kid Rock, Baxter has built a successful second career as a defense consultant.

Baxter dropped out of college in Boston in 1969 to join a short-lived psychedelic-rock band. After that, he moved to California and become one of the original six members of Steely Dan.

You don’t have to be a rocket scientist to play for Steely Dan — but it helps.
