The melody was clearly Norman's. There are snatches of it in Norman's incidental music. Clearly heard after Bond kills the henchman in the swamp. But Barry took that melody and made it what it was.
It was also used by Norman in a musical he was penning at the time.
That is what Norman claims, but he can not prove it. The song "Bad Sign, Good Sign" was never officially released before or after Dr No (at least not after 43 years).
Barry claims that he could only use an extremely small part of Normans work for the guitar riff ("
Nothing leapt off the page as the piece had no excitement"). It was reworked completely by Barry and the beat was taken from his previous arrangements, which are still easy to find. And Barry claims that the bebop part later on all came from him. It is Norman's word against Barry's word.
I don’t care how much Barry changed; it is still Norman’s song and he deserves credit. Norman has said this. Barry has said this. You could perhaps say Barry made it great. Sure, you could also say Whitney Houston made ‘I Will Always Love You’ great, but Dolly Parton still wrote it.
Barry did much more than just arrange the theme so he deserves a writing credit. Your comparison with 'I Will Always Love You' is stupid because it is written by Dolly Parton and she got a credit for it. Whitney Houston did a cover on the song.
And so what if Barry went on to do dozens of great scores, that has no relevance. Look, if you had done just one really great thing in your life wouldn’t you fight for it remain acknowledged that you did. That’s all Norman is doing. Give the man his credit. It certainly does not hurt Barry one bit to not have this one item on his CV.
The JB-theme is one of the most famous movie themes in the world. It is more
nice to give the right person credit for this. Barry's work after Dr No is quite relevant. Norman claims that he wrote the whole theme AND decided that Barry should arrange it. He also claims that the electric guitar was his decision! Now, if Norman had enough talant to create something like this... why didn't we get more like this from him? The rest of his musical work is not even close to this level. However, it seems like the JB-theme fits perfectly into Barry's work. Compare with his previous work at that time ('Bee's Knees', 'Poor Me', 'Black Stockings', 'Beat Girl') and it all makes sense.
In case someone misunderstood what I just said:
"The James Bond Theme" written by Monty Norman.
