1980 Permenant waves tour (February 13, 1980, The St. Valentines Day Massacre) at Keil Auditorium, St. Louis, Mo. Seated 9,100 people and was truly magical!
1. Bytor and the Snowdog
2. Xanadu
3. Anthem
honorable mention: Cygnus X1 Book 1 and Hemispheres concurrent in their entirety.
Then again, am old school, I have seen every song mentioned above (except for The fountain of Lamneth, they never played it) and these 3 as well.
Nuff said
