This week on Three Tune Tuesday, we’re thinking about health — specifically, the kind of health check that requires preparation, a gown, and a level of personal exposure that no one particularly looks forward to. We open with a piece of good timing: “By the Saskatchewan,” recorded on this very date in 1911 by baritone Andrea Sarto, taken from the hit Broadway musical comedy The Pink Lady, with music by Ivan Caryll — who, as it happens, was also born on May 12, making this a double centenary of sorts. From there we move to Rosa Henderson’s 1923 Victor recording of “Good Woman’s Blues,” a spare and dignified classic blues performance written by George Butts and Hulbert Esmere, in which a woman of considerable self-possession states her case plainly, accompanied by nothing more than Wendell Talbert’s piano. We close with Dame Clara Butt, whose vast contralto fills Samuel Liddle’s setting of Henry Francis Lyte’s immortal hymn “Abide with Me” — written by Lyte on his deathbed in 1847 and first sung at his funeral. It is, in short, a playlist assembled in the spirit of a colonoscopy: you go in hoping for reassurance, you endure what must be endured, and you emerge, if all goes well, with a clean bill of health and a renewed appreciation for being upright.
