I LOVE the daytripper riff, and there's some other cool riffs on here too.
Rock on, 60's! Though I was not born then, there's so much great music from there. It's funny, because there were so many good tunes from then that were not all too popular. I watched a BBC show on it. Ok, so it was on BBC, which gives them some popularity... Anyway! Enjoy.
