Adrian was right. This song is best when it is a bit more measured. The sled up versions that got played live don't have time to breathe.
This is a good song, simple lyrics, but pretty standard fare for this era of Iron Maiden. Lyrical simplicity doesn't count so much, not when it's so lovingly sung. But the chorus does repeat - not that the "repeated chorus" crowd notices.
That's an excuse for "I already decided I wouldn't like new Iron Maiden", by the way, the repeated chorus complaint.
Anyway, Flight of Icarus suffers from a few problems. It's simple, like Revelations, but doesn't make up for it in intensity. A great guitar solo, though. I waver between a 7 and an 8, but I'm going with 8.
