Don't know if Dave will come back to this thread, but here's an afterthought:

"I think im going to enforce singing practice amongst the guys and get our vocals in gear." No, no, that's not it!

The operative term in my earlier post is capable singer. De Danann comes to mind as a great tune band who couldn't sing but fostered no less than four great female vocalists who went on to distinguished careers -- Dolores Keane, Maura O'Connell, Mary Black, and Eleanor Shanley.

My point is: keep doing what you're good at, concentrate on the playing, and don't dilute your strong suit with something you don't do well. Instead, look for a comely lass with a great voice and feature her fronting the band. In addition to the sound, you and your audiences will have something nice to look at, as well!

Cheers,
Michael
