Marketwise it evidently fits in very well, since she's a very hot commodity. BTW, I'm not in love with singers covering jazz instrumentals. Usually the lyrics are lousy, tacked-on-after-the-fact affairs. It's not like a composer and lyricist working together. Things like West Coast Blues ('gig out on the west coast, man out on the east coast' or some such) which I'm sorry to say was covered by the selfsame Ms. Allyson, make me wince.
