Kind of Blair Witch in the dark there...love it!
I'm also loving David's added commentary (though the font could be a tad bigger). He's just so funny, and I hope he keeps doing it for that extra comedic touch.
And yes, PLEASE vlog from the bus! I heard his friend say "sweatpants" in response to that--too funny! (Btw, can I just take a sec to thank God for youtube? We would have never seen our fave guy's vlogs a few years ago--and definitely not from his bedroom!! Yes, I look at the bus, and think of it only as David's bedroom! haha!). Back to the buswear: I say bring it all on: sweatpants, ripped wife beater, blanky and teddybear, bigbird slippers, zit cream--nothing can take away this man's sex appeal!!

I hope David keeps vlogging while on tour, and I hope the others do as well. Behind the scenes stuff is neat to watch, especially because it's real and not run by the "powers that be" or some boring interviewer. Also, since they practically put up the Wall of Jericho between the guys' and girls' buses, I think it would be funny if the two buses communicated through vlog. I know they see each other all the time, but it would be entertaining for us fans!! And it's all about giving the fans what they want, right?!! And I want sweatpants, gosh darn it!!!

Quick Edit: About Andy...it's already been mentioned that he was the frontman of Midwest Kings and now fronts To Have Heroes. He is definitely a cutie in his own right. Here's a video I came across on youtube. Andy is waiting in line at Leno's show to meet up with David and is being harassed by some chick, but he's cute nonetheless:
