'That '70s Show' cast reunion photo, it's a sing-along

TV series reunion photos can be pretty scary. “Behold the ravages of time!” and all that. Thankfully, the cast of Fox’s That ’70s Show cast seems to be aging quite nicely. Here’s a pic that co-star Danny Masterson posted on Instagram. Mila Kunis, Laura Prepon, Ashton Kutcher, Topher Grace and Wilmer Valderrama are also all there. Masterson noted, “Every once in awhile friends gather for a 6 part harmony of a Big Star song…” (Big Star wrote the show’s theme song, “In the Street”). That ’70s Show went off the air in 2006. Why isn’t there video for this?
