I'm not a fan of Atom Heart Mother's title song. I think it's the instrumentation that I don't care for. But the songs jdc posted are all among my PF favorites , acoustic, gentle, wise and catchy. At this point, Roger usually gave the songs to Dave to sing, but the song "If" wouldn't be right without Roger's vocal. The other two have Dave's gentle voice crooning, which is perfect for these songs. Beautiful.
Alan's Psychedelic Breakfast is just dull, PF's version of Pet Sounds. It is a fan favorite, but not this fan.
