Now I would never denounce anyone's opinion, but to keep this from becoming a poster board for people's favorite songs, I would like to set a small guideline.
I think Take the Long Way Home, also by Supertramp, has a great intro with the piano and harmonica, but that is more of a buildup to the rhythm of the song as opposed to the intros of the other songs I mentioned which are, more or less, independent from the rest of the song. You see where I'm going? However, post what you want. It should be interesting.
