Ray - What's NP? No Problem? Neils Pederson? Anyway, I understand where you're coming from now. If you played the Real Book version, and then found out later that most folks play it differently, and also the original recording is different, that can easily make you dislike those changes. I don't know what's in the Real Book version, I only included my experience with the Brazilian pianist to say that there are people who know a lot about this type of music who like to play the resolution to C. Not that it's the "right" way, just that it's not necessarily wrong, as some of the stuff in the real book truly is.
Marc - after posting about the changes on that version, I pulled out my copy and gave it a listen again, to make sure I wasn't misleading anyone. One little mistake. The last 2 bars of the first ending are |D-7 |G7 | I usually play it the way I wrote (|D-7 | Abo |) or | D-7 |G7 Abo | so I guess I forgot. Of course, all these variations are very similar sounds/function, but I thought I'd mention it, just so you don't get confused when transcribing Ray's line (that is what you're doing, right?)
Just for a fun aside, this was one of the first albums Ray made with his French bass. Until 1964, he played a big bass, supposedly Italian, but some knowledgable people think it's a big German bass. Anyway, around 1963 or so, he got this smaller French bass, which supposedly sounded better with metal strings, which he was switching to. On this record Ray plays a lot of notes, sometimes I think maybe too many. Very busy playing, and much more in the high register than usual. I think this is a direct result of his changing to a much more playable instrument. On the other hand, the big bass doesn't offer as much agility, but the sound is huge, so it's fun to just play one big fat note. It's an interesting case of the bass (and maybe strings) influencing the way someone plays, although he of course always sounds like Ray Brown, and is great whatever he chooses to play.
Good luck,
Brent
