This…I think there was a realisation on the call that we were not going to get to our collective goal with the current vocalist. The ambition is to be able to do a pub gig. For that we think we need 30 / 35 songs. At the current rate of progress, we will never get there.

As for the tardiness… that’s the harder thing to train…
Absolutely!!

I don’t mind diva as long as they are really diva. Diva usually better than average.
This is an interesting point, @Al1885, fine be a deva, but you better be good! Being a deva and being mediocre is not a great look

LSD- lead singer disorder
. I’ll remember this one!

The not learning the song so you know when to sing those words? That’s unacceptable. And then being late on top of it? Hell to the no. That’ll cost you gigs at some point.
My thoughts exactly…

a mini Axl Rose.
Yeah, but he could rock the house down!! Saw them on the Use Your Illusion tour, bloody fantastic!!

You don’t know the song until you’re leading the song with your part.
While you put this far better than I could, @Gio, I was thinking something along the same lines. Playing to a backing track, you effectively have a road, rolling out in front of you, you can “see” it. Playing live with others feels more like you’re having to lay road as you’re driving along it. You have to know your part ‘cos the cues might not come, that little tap of the cymbal, that little guitar fill… Plus you are the cues for your band mates. It’s a really interesting process…

being the first time on stage
This was our third time, @MattyD, plus a fair number of rehearsals…

Maybe your singer just wanted some fun and never planned to treat it more professionally.
This could be part of it, @saroohoo. I think the main issue is that to get to the level you need to get to, not professional, but able to hold it together, play tightly and put on a bit of a show, takes practice. I play at least an hour a day. The guitarist, the drummer, the same. The singer? I think it’s just bit of singalong in the car… what I found interesting was talking to a couple of other vocalists; both mentioned taking vocal coaching. The current / former vocalist would never entertain this.

You are more the Happy Meetings kind of guy
Ha!! In all seriousness, I work. The drummer works (runs his own IT company). The guitarist works (a CFO). Time is precious. I often say to clients, let me sit in a few of your regular meetings, and I’ll tell you what’s wrong with your company. Meeting are a window to the soul of the enterprise…

If they’re not going to take this seriously then invest your time with others that really want to do it.
Exactly this…!!
