Listen to this. (it's the same take as the studio version but with louder bass mixing). Listen to how almost every single two bar set is different, and he just goes nuts with the improv in the second half of the song. Insane. Also, I can't imagine him actually memorizing the Lemon Song bass solo. It's just too long, unstructured, and erratic it seems. What scale does he use in it anyway? Love the note choice.
