This is something that I've been wondering about for a while now. Basically, when playing a jazz standard, or any well known song in a jazz context, how would the song generally be interpreted? For example, say that your bandleader decides he wants to do Giant Steps. How would you generally go about preparing for this - would you listen to different versions, perhaps leaning heavily on one definitive take, or would you just find the changes and take it from there? I know that this is probably something that differs from person to person, and that I've probably unwittingly made a complete fool out of myself somehow by asking this, but please just humour me, ok?
