Good Hobbit Morning chapter 15 "The Gathering of the Clouds"

"One morning, the dwarves saw a company of elves and men approaching the mountain from the south. From behind the stone walls the dwarves had reared in front of the entrance, Thorin spoke, asking "who are you, arriving as if for war?" But the newcomers said nothing, and returned to their camp. Soon the Company heard the pleasant sounds of Elven harps, and Bilbo longed to escape the cavernous halls under the mountain and join in the Elven pleasantries. In response, the dwarves took up their instruments and began to sing songs pleasing to Thorin. But Bilbo was dismayed, for he perceived their talk and their songs to be too like to war-mongering.
The next morning, another company of elves and men approached the fortified Front Gate."
