In regards to Jorn—and let me say I love Jorn's voice—I think Tobias have gone a little too safe with Jorn after The Scarecrow. I felt that from The Wicked Symphony onwards, Jorn was more like a given on Avantasia albums, and then the time had come to record The Mystery of Time, and Tobias totally had Jorn in sights, but then Jorn said "hey, I can record the studio vocals but I won't be there for the tour". Tobias then had to find other singers for that album, and I thought that was a much needed breath of fresh air for Avantasia; for I can't imagine Jorn performing anywhere on TMOT except maybe Invoke the Machine.
Then Jorn was back for Ghostlights, and as far as I'm concerned, Lucifer notwithstanding, even though Tobias cut down his participation for the actual vocal duties, that album was Avantasia by numbers, and while for other bands that would've been sufficient, I've got higher standards for anything Tobias is releasing, because he himself set the bar at its highest. And, well, I know that Ghostlights is the most critically acclaimed Avantasia album. I just hope Tobias doesn't give a shit about that, and that he will write and record whatever he wants.
I'm kinda rambling. I'm not saying that I don't want Jorn on Moonglow, I'm saying that I want Tobias to maybe explore some new grounds with this album, or at least to not stick to the tried-and-true formula he used on some previous album.
