Now I'm using Lanomax, I found a cheerful tune that makes me feel a lot better: "I'm Beginning to See the Light" Here it is, beautifully played by Sonny Stitt (as), Lou Levy (p), Paul Chambers (b), and Stan Levey (ds): https://www.youtube.com/watch?v=4f0hNWHrvQk
I don't think either Duke Ellington, who composed this tune, or Sonny Stitt, were thinking of cataract patients when they recorded this, but I hope it will make other Lanomaxers feel better too, during the long wait until we do see the light again.
