What is the epic song of a group?


I will start. I vote for Stairway to Heaven for Zep. Its grand with a great finish. I will throw in Salisbury by Uriah Heap. Ok lets see some posts of what you think is a groups masterpiece.

Al, speaking for myself, that’s because very few groups have a member capable of writing what I consider a song, let alone an epic one ;-). By the way, though I don't care for Joni (to put it mildly), I agree with you about Judy’s version of "Both Sides Now" ---Eric.
