Good Hobbit Morning chapter 19 "The Last Stage"

"Bilbo and Gandalf arrived in Rivendell on May 1. They were warmly welcomed by the elves, and Gandalf spoke of their adventures, while Bilbo listened. He learned that Gandalf had been to a great council of the white wizards, and that they had driven the Necromancer out of his domain in the south of Mirkwood. Many other tales were told during that evening, until Bilbo's head was spinning, and he fell asleep."
