First of all I think I goofed . . . Lawrence's tune ("you see it's alll cleah, you were ment to be heahhhhhh") is called "From The Beginning" . . . Lake wrote quite a few of those CSNY-jazzy-dribbly cosmic oh wow tunes, it's easy to get them all confused. ;-)
The "please please open your eyes" bombast is also on Trilogy and is called "The Endless Enigma"
