How much time do you usually spend to learn a 'new song', including the time required to prepare it for performing on your arranger at the gig? This includes:

- melody & chord memorization, + arrangement licks (by ear or chart);
- lyrics memorization
- selecting, customizing, tweaking an arr keyboard style, reg settings, etc.
- any other things to have the song nailed for gig performance

Any tricks of the trade to share?
