Iggy Pop defends writing about penis

Rock legend

Iggy Pop insists writing about his penis is perfectly natural, because he wants to sing about "things of importance."

The 60-year-old Stooges frontman and protopunk icon has been lambasted by critics, including his former NME writer pal Nick Kent for writing songs about his appendage on the Stooges' latest album The Weirdness.

For example, opening track "Trollin'" features the lyrics: "My d--k is turning into a tree."

But Pop is adamant his penis has a place in his music.

"You write about things of importance to you," he tells Rolling Stone magazine.

"And it's gotta be for real. Do I think about my d--k? All the time. I got a right to [think to] sing about it. If I thought, 'It's time to write a rock song, I'd better mention my d--k,' then I wouldn't even be able to say 'd--k' right. But it's nature-oriented."
