WASHINGTON (AP) — The Smithsonian is putting together a collection of rock and roll photos and has realized the best shots could be the ones from the audience. The Smithsonian is asking the public to submit their photos from the rock and roll era to the website RockandRoll.si.edu. Some photos may be featured in a book to be published next fall. Graham Nash and Flaming Lips are among the musicians who will contribute photos and comments.
