All of the above, basically, except the junkie/thief and the dead guys.
Trying (actually, about done) with a brand new start-up. No auditions, the drummer herded us together from Bandmix. We are all new to each other.
No one wants to learn new music. Every one wants everyone else to learn
his songs. Every session (4 so far) there's a lot of "Anyone know this one?" and off he/she/or they go, usually all the way through. Mostly the expected instrumentalists who always do that, but even the drummer will just start playing and expect us to know the song and jump in.
Last week, right after practice (definitely not a rehearsal), I compiled a list of all the songs that had been suggested (I take notes), emailed it to everyone, and suggested that we each pick
one song. On the list or off the list. Any song; one each, to learn or work up for our next session. The singer suggested "Flirting with Disaster". I suggested "Going Down", Freddie version. Neither on the list. That's okay.
One guitar player suggested: "Won't Back Down", "Lie To Me", "Cold Shot", "Those two songs by Black Crowes", "Broken Hearted Savior", "Low Rider".
The other never responded.
Drummer: Cream: "Born under a Bad Sign", "Spoonful", "Crossroads" and "White Room" (wonder what he was listening to??)
Half of these, I have down. Familiar most of the others; charted out "Verse, Verse, Chorus, signature licks, etc". Learned a couple from zero.
Needless to say, we showed up, everyone knew what they already knew, nobody worked on anything, and we did: "Anyone know this one?"
BUT!! I'm back in the music room, learning tunes, perfecting (well, you know) some I kinda knew, playing music. I'm going back next week, too!!

I'm sorry, what was the question again??
