Hi Lee,
My advice? Get your nose out of the book, and listen to his live recordings of those same tunes. Charlie was FLUENT in all 12 keys, and was nothing less than a wizard, both as a saxophonist and as a musician in general. He could compose on the spot (IE improvise) with greater clarity and creativity than any other single musician I can summon up.
A Major component to Be Bop is the variety and lines of rhythm, which is high near impossible to translate exactly, or effectively, via music notation.
Still, some don't "Get" Be Bop, and like any other musical genre, it comes down to personal taste and preference.
There are certainly Jazz artists of the present and past, with whom I don't understand the public hoopla lauded on them either. Bird for me, ISN'T one of those.8)
Cheers.
