Duff McKagan’s column runs every Thursday on Reverb. Follow him on Twitter @Duff64.”Is this a Mr. McKagan?” said a voice on the other end of my telephone.”Yes,” I replied, thinking it was a telemarketer who had somehow gotten my cell-phone number, and I gripped for a pitch. “My name is Kenny M., and I work at American Airlines. Are you missing a black bag?” And so began the conclusion of the mystery of my lost black bag, gone for some 17 days after an Iberia flight from Prague to Pamplona, Spain.Kenny M. was calling from Dallas, Texas (nowhere near Europe) and American Airlines has no relation or partnership to Iberia Airlines. My bag just showed up one day, with no ID card, at Americans’ central baggage service depot. Kenny said that apparently my bag had been around the world, and that in circumstances where there is no ID, he must get inside the bag and look for clues. In a vest pocket, he found a receipt for a Hilton at the Helsinki, Finland airport … he called them. Luckily for me, I had filled out a Hilton Awards card at that Hilton on that stay and they had ALL of my information, including my cell-phone number.I know when I wrote about my lost bag last week, some of you responded that it was just a material possession and that at least I was healthy and blah, blah, blah. But in this bag, there was all of my good-luck rock gear:1. My leather bracelet that I’d worn for every gig in the past six years.2. My “Chrome Hearts’ leather vest given to me by a close family friend and worn at every gig I’ve played over the past three or so years.3. Gloves given to me by Hanoi Rocks’ Michael Monroe.4. My ear-infection medicine (a rock-tour staple).5. Rock pants.6. Smell-good stuff (another rock-tour staple that staves off the scent of a wet leather vest and bracelet, and not-too-often-laundered rock pants).7. My gym clothes and Nike tennis shoes.8. Shave kit.So, when I went down to FedEx on Alaskan Street to pick up my bag (NOT Alaskan Way as I found out after driving around SoDo for 45 minutes), I was a bit amused to find my tennis shoes missing and my medications strewn throughout my bag. The FedEx guy there informed me that customs or airline personnel will often do this with someone’s medications after they find that there is nothing that will either get them high or that they can sell to a drug user. The missing tennis shoes were new, and I suppose some jackass down there wore size 11. What most amused me about this was that the leather vest that made it back to me unmolested was worth $5,000! That vest was the pure and simple reason I thought the damn bag was gone in the the first place. Suckers!A Little Green DayLast week, Green Day came to town, and I have become a big fan recently after I saw their alter-ego band the Foxboro Hot Tubs at the Roxy in Hollywood last year. The FHT showcase how good. Mike, Billy, and Trey’s musicianship is AND how loose and fun rock-and-roll is supposed to be. Green Day know how to write the hits. And after seeing them live, it’s obvious that they’ve somehow maintained a punk ethic well into mainstream success. As a fellow musician, I appreciate the art of writing a good song, and that is what these guys do so well, time and time again. It was a great gig for sure, and impressive to see KeyArena sold out.A Little RantI read posts to this column and others, made so often by anonymous people, that they don’t like this band or that. While I certainly applaud a person’s free will and opinion, it gets tiring to see a person so chickenshit as not to put up their own e-mail or at least first name and last initial. If you have opinions about music I talk about in this space, at least have the balls to ID yourself … I do. Moving on …A Little Music This weekend, I hope to see two shows: Roxy Epoxy at El Corazon on Friday, and70 Proof at the West Seattle Street Fair on Saturday.A Little SunI have gone east for the week, choosing to start my well-deserved summer vacation up near Lake Chelan. My daughter Mae is upstairs in our cabin right now, playing an old acoustic guitar that I brought along. We hope to get a boat and go “sea couching” later today (a “sea couch” is our name for anything larger that an inner tube that we can pull behind a boat and floats).Happy Summer to everyone reading this. I am pleased as could be to be back home after so much time away. My family have returned to our normal place and that is, at this moment, a place in the sun.
