Who do you turn to for advice — Dear Abby? Dear Prudence? Carolyn Hax? Why not rocker David Crosby?

A whole bunch of people read advice columnists, seeking wisdom on everything from infidelity to in-laws. Whether it's Dear Abby, Dear Prudence, Amy Dickinson or Carolyn Hax, people love to hear what advice columnists have to say.

Well, now, a new player has entered the fray. And it's a bit of a shocker — because he's a rocker.

Rock legend David Crosby has, well, yes, become an advice columnist, sharing his opinion on everything from open marriage to whether or not it's wise to vaccinate your child (or woefully stupid not to).

Crosby has his own special role in Dallas history. The first name in Crosby, Stills & Nash got arrested in Dallas in 1982 for felony possession of cocaine. Having a handgun with him only worsened the charges. But when we caught up with Crosby in 2014, he said the drug bust in Dallas "pretty much saved my life." Crosby headed to the Texas State Prison, and that, he said, helped him get clean.

Getting busted at Cardi's, a now-defunct club at Medallion Center, was "not a pleasant way to get off that train [of drug abuse], but it worked," he told us. "As a matter of fact, a very tough way, but it worked."

You can read Crosby's debut column here, in Rolling Stone.

"I think it's very funny that anyone would ask me for advice about anything," Crosby says in a YouTube video promoting the column, "because I'm kind of crazy."
