One thing I do on endings that is greatly appreciated....Generally speaking, I try and let the bandleader signal the last note in an ending. I don't like seeing a guy with his guitar neck perched in the air waiting for the drummer to finish his flourish. Tells me the drummer isn't looking around at that most crucial time. When I see that guitar neck go up, I end my thing no matter where I am in it to catch the last note. It looks much better when the bandleader signals it. Don't leave the bandleader hanging when he's trying to cap it off.
