Dave Grohl told the epic story of meeting Paul McCartney in his autobiography, "The Storyteller," and a Medium post titled "Entering Valhalla." It starts not with McCartney, but with the son of another Beatle. Grohl says that he was chilling backstage after a concert when a familiar-looking person was escorted in to meet him: Dhani Harrison, George Harrison's son. It was 2002, he was in the middle of organizing a tribute concert for his late father, and asked Grohl if he wanted tickets and after-party passes. He wrote, "I've never been to a party that I couldn't have missed. Except this one."

He wrote about hanging out, seeing old friends, and then? "I noticed Paul McCartney out of the corner of my eye, chatting away with friends, and I couldn't help but stare. There. He. Was. I don't know what it feels like to see a UFO. I don't know what it feels like to see a ghost. I don't know what it feels like to see Bigfoot, but I know what it feels like to see Paul McCartney, and if that's not a supernatural event, then I don't know what is."

Actually meeting McCartney came not long afterward, and Grohl says that he was so starstruck that he couldn't remember much about what was said, or even who introduced them. It was, however, the beginning of a long-running friendship, occasional partnership, and heartwarming story.
