"They Say It's Spring" from the 1958 album Give Him the Ooh-La-La. That's Blossom Dearie, piano and vocal; Herb Ellis, guitar; Ray Brown, bass; and Jo Jones, drums. (I don't know if it's true now, or if it was ever true, but it used to be said that Ray Brown was the most-recorded musician of all time. He certainly never wanted for work.)
