So, I've been spending time and thought in this era, and I thought I may as well share the experience.
The videos below are from 1975: Talking Heads, "SOS" by ABBA, and the trailer for "Jaws." There's a link below those to watch "Pinball Wizard" by The Who, if you want a bonus video to go by; embedding of that video has been disabled so I can't post it here.
The prompt instructions for this week: watch each of the videos. At the end of this post is a photograph of regular people in 1975. Use these characters - one, a pair, all of them - in the time (or place, if you'd like) and write like it's 1975. You can do it. Give yourself 10 minutes; 15 if you're on a roll.
