In the Season 6 episode, Witchstock, Paige, Piper, and Phoebe go back in time to the year 1967. Paige goes back first by wearing a pair of Grams's go-go-boots, which Grams had put a return to owner spell on. Piper and Phoebe decided to go back as they need Paige for a Power-of-Three spell in 2004. It was also the year in which Allen Halliwell, the Charmed Ones' grandfather, had died when he was double-crossed by Penny's friend, Robin (but after being save by Paige, he was killed by a demon).
