Good for you guys.  Sometimes, it's really tough to make those decisions.  It's about what you are looking to get out of the band experience.  If you all felt the same way, then you make the tough choice. BTW, I can't get the link to work-maybe you should check it.

I was (hell, still am I guess since I'm playing with them in May) in a band in college. The singer was the greatest, sweetest guy in the world, but not the best singer.  We talked about it a few times, but never went forward with getting another singer.

He's a buddy, though and a lot of fun and the band wasn't serious, though we could have been signed given what was going on in the scene at the time.  No regrets there.

This band is a completely different thing. We've worked very hard and want to take this where no previous band we've been in has gotten to, so that means everyone has to be excellent.  We were very lucky to have our last singer-a good friend, who now understand why we did what we did.  We needed more than just a good voice-we need a professional attitude as well.

We've still got work to do, but we're getting there.

Good luck with your new singer!
