Music towards the end of Audi "summer camp" commercial?

Hi everybody. I'm sure you've all seen this commercial countless times by now, and are probably just as tired of it as I am. Having said that, I was wondering if any of you recognize the music - presumably a classic rock piece - which starts playing 19 seconds into it? If you could tell me the name of the artist and song, and/or provide a link for said song, that would be great. Thanks in advance. Here then is the commercial I'm talking about: http://www.youtube.com/watch?v=k3P-X8vcK3I
