I just wanted to comment on the Arrival "leftovers" thing. I think that calling them that kinda implies that they weren't good enough to make the album. I know that both the band and crew that worked on the album were shocked that "Walking Away From The Edge" didn't make it and so am I.
I think it's a very beautiful and deep song, and had I been John Kalodner or whoever the A&R guy was that made that decision, I definitely would have included it on the album.
"World Gone Wild" originally wasn't included either and once again I can't see how anyone would make a decision to leave it off. It's melodic and heavy/hard rocking and one of my favorite Journey songs ever and Neal's solo is simply awesome.
I know that all the songs you guys are talking about haven't been specifically confirmed by the band as coming from the Arrival sessions, but those two have been and originally didn't make the cut.
Anyway, I just wanted to say that maybe the term "leftover" has a kind of negative connotation.
