I just saw this video on YouTube and thought it was very interesting. Jim "Harpo" Valley of The Raiders attended a Beach Boys concert at the Seattle Coliseum, December 27 1966, and on the recommendation of Terry Melcher had a "gift" to deliver to Dennis Wilson. But Harpo unfortunately ran into some cops in the process...Then Harpo gets invited to hang out with Dennis, Carl, and Brian right in the middle of the Smile era, and got to experience Brian's tent and the sandbox at Brian's house.
Very interesting story, maybe Harpo can be persuaded to give some more info about these adventures?
For Ian Rusten: Perhaps consider adding some of this detail to your gigs website for the entry on this 12/27/66 Seattle show? Pat O'Day, who is listed on the poster you've reprinted on your site for the show, was one who had to save Harpo from the cops that day.
