Let's see... the late 60s/early 70s are an interesting time to associate you with. I can't remember all the options from that quiz (although when Quizilla is back up, it's on the 'latest quizzes' page). Answers besides Hendrix were people like Jim Morrison, Janis Joplin, Grace Slick, Ravi Shankar, the Beatles...

However, I am giving this very careful consideration. You are very loyal and dedicated, but you also have quite the rebellious streak. You have a political conscience and are not afraid to speak your mind. Yet you're also very fun to be around with a great sense of humor. Therefore, I hereby dub you an answer that was not on the quiz and declare you to be Country Joe and the Fish.

I have to admit, I'm torn here. But it's one, two, three, what are we fighting for? You're an anthem, sister.
