Ask which songs he wrote. (And, if you can sneak it in, which songs John Myung wrote.)
What kind of things has he chosen to write about? Are there any subjects that he really wanted to tackle with this album? Can he see himself contributing more lyrically in the future, now that there's more space for it? What sort of discussions go on, when choosing a song to write lyrics for - are there any that he had an idea for but didn't get a chance to write?
(Oh, and does he remember the working titles to any of the songs for this album? Working titles are dead fun, typically.)
ALSO - how did they choose the setlists this tour? Was it more of a collaborative thing? Were there any songs that he really wanted to slip into the set? Are there any songs they've not played in ages that he'd like to have another go at?
There we go - loads of lyrics questions, loads of setlist questions. Not many about actual vocals - sorry about that. I'm dead interested in what the dynamic was like, recording with Rich Chycki - did he feel he had more freedom to put his own stamp on it? And how have they dealt with vocal melodies this time around; did he and Rich Chycki work them out themselves from rough guides, or have the lyricists written the melodies again? (Back to lyrics!)
(That, incidentally, could be why JM's contributing again. He doesn't really "do" vocal melodies, but if JLB's designing his own to an extent, then it doesn't matter, p'raps?)
