ah, so the word is VIBE! That's been bugging me, couldn't figure it out haha.
Yep!  "Vibe" sounds cooler than "life", which was what I initially thought I heard at the show.  When I came back and started catching up on the forums, it was amusing to see people speculate over what they sang.  Life, vibe, bite, bike???  

  I'm glad I didn't know about that til now, otherwise BIKE would've definitely been forever stuck in my head.  (Kinda like how I will always sing "Let me tell you honey I just wanna love your hedge" in KMKM.)  

..."love your hedge" is still fitting, no?
