I will not tell you guys everything from my trip, but I will tell you all my prog related experiences I've had during the amazing Led Zep trip.
I got to meet David Gilmour while I was exiting the venue. One woman was so excited to meet him she fell off her heels and Gilmour actually picked her up! It was hilarious! I have a picture with Gilmour, which shows him signing a piece of paper I had taken from my hotel. I took some albums from my house before going to London to see Zeppelin, and ironically, the classic band I forgot to take was Pink Floyd XD.
When I was on my way back to the airport, I saw the pig from the Animals cover above the Battersea Power Station. Apparently, the Simpsons: The Movie DVD was released the same day, and in honor of the Animals cover and Spiderpig from the Simpsons movie, the pig was hung over the Station. They had snipers surrounding the place, in case the pig escaped, which did not happen while I was near :(.
