Steve, et al ...
This is what I would do if I were you:
Cemetery Gates (opening) (brief pause)
Temple of Fire (no gap between this and next song)
Soulfire
-talk to crowd-
Far Away
For Evermore (keep pause brief here)
Diamond Sky
-talk to crowd again here, say a few cool things, but don't stop the music, keep the keyboards going and go right into ...-
Neverworld (closing song)
You don't have time to mess with an encore, just play your whole set and we'll be left wanting more ... because you guys are awesome!
Now here is the deal - when you play NEVERWORLD, you have to be sure you get the entire piano outro going and you guys come and do your "Thank you ProgPower, we will be back!"/joint bowing during the outtro but you have to leave BEFORE it finishes so that the last piano chord hits us with an empty stage. THAT WOULD BE SO F**KING AWESOME, I WOULD DIE!!!
Gee, I haven't put a lot of time into this or anything, have I?
I love you guys!
