“Anyone that writes for a living knows what I’m going through,” Stephen Stills tells Rolling Stone.

The guitarist is the last member of Crosby, Still Nash and Young to release a memoir, and in addition to technical issues Stills is having, attempting to type on a laptop while riding a tour bus, he’s also having trouble accurately remembering the timeline and details of his career.

“All this stuff is compressed into 18 or 24 months. I have to get it all straight. Also, I went to five different high schools! I have no idea why. My father was up to something.”

So Stills says he will stick to the funny stuff. And he’s doing it alone. Unlike most rock stars writing memoirs these days, Stills is doing it without a ghostwriter.

“I got an 800 verbal,” Stills says of his SAT results. “Dammit, I’m writing it myself.”

Stills has recently finished up a number of solo dates and hits the road this week with Crosby, Stills and Nash for a US tour through early October.

Carry On, a retrospective 4-disc box set spanning Stills’ 50-year career, was released earlier this year.
