Mick Jagger's eclectic reading habits

This is totally random, but I’ve always thought this interview was funny, ever since I came across it about a year ago.

It’s the Rolling Stones’ 1981 tour, in support of Tattoo You. The interviewer asks Mick how he keeps himself entertained during the inevitable downtimes of touring, and Mick says he reads, mostly biographies and novels. “What’s the current biography?” the interviewer asks. “Bernard Baruch,” Mick answers.

Bernard Baruch?! Mick Jagger, lead singer of the Greatest Rock ‘n’ Roll Band in the World, Mr. Jumpin’ Jack Flash himself, the darling of millions of rebellious teenagers, in 1981 spent his spare time reading about Bernard Baruch, early 20^th century financier, advisor to presidents, a man who practically defines the Establishment?

Rock and Rolllllllll!!!!! Not. Yet somehow it fits.
