This is hard; I cut it off with no Squire and/or no Anderson. Not hard and fast, because I left off Heaven and Earth (though Squire appeared on that) and I included Drama, Fly From Here, and From A Page that didn't have Anderson. Obviously something off GFTO versus something off The Ladder is an easy choice, but to discern between a song from The Ladder and Magnification, not so much, or a song from CTTE and Fragile...
