He pointed me to the source of the rumor, a Portland blog, at which the following was posted:
While out walking N. Mississippi, I noticed the old Richard's Housewares lot has privacy fencing up and a security guard. Also, there are porta-toilets in the back. After asking around, I learned that there may be a private event occurring there this evening or Friday and the performers are the Beastie Boys. Yep, you heard it here first. I have nothing to back this up other than hearing it from people who work or own businesses on the street.A reader of the blog provided additional information, quoting an inside source who says it is the Beastie Boys playing a corporate gig for Wieden & Kennedy, a Portland-based advertising agency. BS or not? I have no idea.
Although I think this rumor is highly improbable, I'm posting it in the event that it pans out to be true and/or someone has concrete evidence to either confirm or dismiss the rumor. If you know something, hit our inbox with an email.
