If you squint hard, you can see it, there amongst the images of Dresden, Arizona, before the dreadful bombing.
And look! Good news! A billboard for up-and-coming Lite Rock radio station KBBC! On June 13, 1976, their Number One hit was "Afternoon Delight" by the Starland Vocal Band! Though it would soon be toppled by Peter Frampton's "Baby, I Love Your Way," which would hold the Number One slot until it was finally knocked down to Number Two by "Don't Stop (Thinkin' About Tomorrow" by Fleetwood Mac in August 1977; the two songs would remain Number One and Two in Phoenix until early February 1997, when they each fell into the bottom of the Top Ten.
But there 'tis. (Oh, and the sign next to the KBBC billboard says "Arizona Awning," not "Yawning.")
