As a reference, you can hear Oscar himself play the solo in this YouTube video starting at about 0:31.
I notated the transcription an octave lower for ease of reading.
You can play it an octave up to be in the same register as Oscar's solo.
However, I transcribed the solo in G, as the version on my CD seemed in G.
But this video recording seems to be in Ab, or somewhere in between G and Ab.
Nevertheless, Oscar's solo is stellar!
Flawlessly executed at about 196 bpm
