First off, I'd tell your lead guitar player to "go pound sand." Life is too short to have to put up with some prima donna who's a Jimi Hendrix wannabe.
Oh..and in regards to "noodlers." I'm thinking that you're meaning that they're clowning around on their instrument while the rest of the band is waiting to either start a new number or are trying to get something accomplished. To me, that screams "UNPROFESSIONAL!" You don't waste time with those bozos. Tell 'em to go join a garage band somewhere where they'll be happy and be with folks of their own caliber.
This particular lead guitarist once turned up to a service club (private members club with bar and restaurant, bread and butter venues for Kiwi bands) gig with an
accoustic guitar instead of his electric. It was the last gig that particular band ever playe.
At our last outdoor gig we spent an hour going over our 40 minute set, working out what each song intro was and which guitarist would play what, only for our "lead' to ignore it all and play just what he wanted to. Luckily we had a fill in harmony/rhythm player who adapted quickly and well to the changes. This would be our preferred lead player but he is unable to commit to our band.
As to your comments about being "professional" I whole heartedly agree.
I am well aware that this is a "hobby band" and will not make any of us rich, and yet the core of us agreed long ago to be as professional as we can be in all aspects of the band.
We spent around 5 hours today going over our setlist for the end of the month. We made sure we all had the introductions and endings of the songs organised, even those songs of our absent members. We changed a few song keys that seemed to work slightly better vocally, and got in sync on background vocals and harmonies (I really can't sing harmony, I usually take over the lead line, but I try. In fact I am very trying



).
We all came away at the end absolutely tired and worn out, but we
then spent an hour together going over our charts, ensuring that all corrections were the same and working out a list of songs to practice before club day on Saturday when our guitarists will, hopefully, turn up early.
This evening I corrected and reprinted my charts that had wrong chords or key changes, printing out enough copies to correct all chord books on Saturday.
