The Carlisle guys did change their name; In LTMP 7 it's mentioned briefly by Helen:
QUOTE
The guys had a similar situation when Instinct formed; their last name was originally a real tongue-twister, but they adopted ‘Carlisle’ as a stage surname. When the split with their folks occurred, they decided to change their legal names to match. Therefore, when I saw your name...
I'm not saying who JT is (we find out in Ch 2), but it's true that Carlisle is not the name Jon, Eric, and Chase were born with.
Eric's sexuality is kind of vauge here, but it was in LTMP too, in some ways. Nothing has really changed.
In LTMP 35, (Don't Tequila the Eric)

Meeting his brother’s eyes, Eric’s smile faded as he said, “Yeah, after we named the band and Jon passed out, you and me had one of our talks. We named the band ‘Instinct’ because of me being able to read people sometimes. I also remember telling you that I sometimes find guys hot, but chicks are hotter.”
Chase reached out and Eric returned the gesture, meeting Chase’s hand and hooking fingers. Chase angled his head, giving his brother an inquisitive look and asked, “So how come you pretended not to remember? What’s the big deal?”
Still holding onto his brother’s hand, Eric smiled faintly as he replied, “I don’t really know. I guess I was a little uncomfortable with that part of me. You and I are so alike; almost twins, hell even more.... I guess I wondered if I was going to be gay too.”
Oh, btw, Rknapp, my villains aren't nasty. They're just a little.. misunderstood.
(for anyone wanting truly evil villains, go read Shadowgod's stories; he's evil, I tell ya, EVIL!)
Now, about the Peperoni and banana sandwich. I changed it to that because I felt it sounded a little better than my personal favorite; Peperoni, peanut butter, and Tobasco Sauce sandwiches.
Actually, Jon, like his brothers, has some slightly eccentric tastes in food.

Oh, about the title... Yep, it's been in the text already, BUT... Don't forget, it could mean a lot more than the name of the new album. There will be other meanings beside that, but that's not for a bit yet.
