I love this solo, and I could never find a transcription that I was happy with. Mine is still not 100% but it's getting closer.
My performance is also not 100% accurate to the transcription ! - it's still hard for me to play even at this tempo.
Django's finger-style intro is included in the tabs, though I do not play it in the video.
