Time constraints were a huge factor. This is always the case with a band, but these constraints became more serious with the limited lifespan available to this band.
Lives don't just stop, either. Everybody had something going on, something major, different from the other members. In the end these things took precedence.
August came too soon. The window closed. The opportunity passed.
Will it ever happen again? Maybe. Possibly. Who knows? Everybody is a little bit older, a little bit farther along their lives' paths. Responsibilities make their demands. Deadlines and commitments. Planes to catch, and bills to pay.
And someday, maybe these people will once again say "Screw it all. Let's start a band."
