man, we must be brothers! i'm sucked into the "working man" role also, along with being formerly married and giving up a perverted amount of check to child support! hemispheres blew me away as well! i learned that entire album and still play it today. it was and is an exercise in chord theory!
but as for my favorite song, i dont have one, i have many! but heres a few....
1. hemispheres (the whole song)
2. la villa strangiato
3. the camera eye
5. natural science
6. losing it
7. here again
8. by tor and the snow dog
.....and on and on and on......
