I'm surprised I haven't seen any songs that were from their 1967 album, The Piper at the Gates of Dawn, when Syd Barret was still in the band. If you guys thought Dark Side of the Moon was trippy you should hear some songs off this album. I'd have to say one of my favorite Pink Floyd songs would be "Pow R. Toc H." and its on the piper at the gates of dawn album.
