Since you might be interested in the first appearance of Barack Obama and Joe Biden together after the announcement of Obama’s decision, I will include the full event (August 23, 2008 in Springfield, Illinois).
Part 1 and 2 of the recording is Sen. Obama’s introduction. The last minutes of Part 2 and Part 3 and 4 is the speech from Joe Biden.
Huffington Post provides a transcript of the Joe Biden speech.

The Rolling Stone compiled a list of their Top Five Rants of Olbermann.
