Michael H. mentioned, in another thread,
"Actually, Django did have some independence of the 3rd and 4th finger. Not much, but he seemed to be able to place them one fret apart on the higher strings."
I know the canard about him having no use of the 3rd and 4th is false, but how did he use them? Was it just when he was grabbing chords?
If I'm ever going to be able to play just like him, I need to know!
