THE CAST OF THAT '70S SHOW

Talk about a blast from the past: Seven years after the sitcom ended its eight-year run in 2006, Topher Grace, Ashton Kutcher, girlfriend Mila Kunis, Danny Masterson, Wilmer Valderrama and Laura Prepon partied like it was 1976 all over again at an Oct. 8 get-together-turned-karaoke session in Los Angeles. "Every once in awhile friends gather for a 6 part harmony of a BigStar song," Masterson captioned the snapshot on Instagram in a nod to That '70s Show's theme song.
