The first of three 40th-anniversary issues of Rolling Stone is on newsstands now, and it is overflowing with the witty Q&A interviews that make the magazine frequently worthwhile. There’s the requisite kissing of founder Jann S. Wenner’s ring, as nearly every interview involves a moment when an artist describes how important a role the magazine played in wide cultural transformation. The next 40th-anniversary issue will focus on the Summer of Love, and I can imagine people discussing how many times a stray Rolling Stone on the coffee table helped them get laid.
