I guess I haven't got the finger strength to get a good sound out of a barre chord like I used to be able to do. I tried the method of using my thumb on the base note, but that didn't work much better for me. I've been practicing this every day and my left hand is sooo sore. Does anyone know any way around this. I will keep practicing my barre chords, but in the meantime, I'd sure like to play this song all the way through. Thanks for any advice or just plain old commiserating you care to share with me.

BTW, I play this on the guitar on the left hand side in the pic. And old 1960 classical.
