Siberian Khatru by Yes is usually the first song on the playlists I listen to during my walks. High energy, kick ass song...by the time it's over, I'm more than a half mile from my house and ready to go 7-9 more miles.

“Pirates” ELP
Hard to find any decent live versions of YES or ELP. I think 1) concerts during prime years are old; 2) the complexity of the music is difficult to get.
