I listened to Octavarium from the Score DVD yesterday and in between stuff I can't decipher I'm sure I heard James Labrie listing Beatles songs.
Off the top of my head I can remember 'Lucy in the Sky With Diamonds' being in that verse.
Yes. He's the whole verse:
"Sailing on the seven seize the day tripper Diem's ready
Jack the Ripper Owen Wilson Phillips and my Supper's ready
Lucy in the Sky with diamond Dave's not here I come to save the Day for
Nightmare Cinema show me the way to get back home again"
It's a pretty damn weird part of the song. It was a game that Mike Portnoy came up with, to connect song titles and pop-culture phenomenons to each other in a way that it almost makes sense but not really.
