Working a piano/bass duo Saturday, crowd was noisy and self-absorbed. It was late, a boring night, we were going to play It Had To Be You, medium up. It started as a joke, but we played it in B natural. I recommend this for brushing away the cobwebs and avoiding cliches. Especially good with standards, i.e., a tune with real changes and not a two chord vamp. Besides, you never know when you'll have to do this for a singer.
