As far as adjusting for singers goes, key-wise, again, if your function is simply back-up, sure, you learn the song in his/her key. But, if you're talking about an established group, particularly, a jazz group, in my world, the singer either sings in stock keys, or you get another singer. I am not going to adjust all arrangements to compensate for the requirements of a vocalist, unless that vocalist was the headliner. To do that, you would have a problem every time you had to replace ANY player. The new person would have to re-learn all tunes in keys other than stock. \That is a time-taker and not the way business as I know it is done.

Now, getting back to the Chas' previous reference to Diana Krall and Alicia....ANY KEY IS FINE!
