Client wants to own the copyright - what do I need to declare?

For the first time in my 20-year career, I have a client wanting to own the copyright for the animated video I've made him.

I told him I am happy to give him copyright for the video, but now he's saying that he also needs a list of all the software I've used to make the video. Apparently he was advised by the FSB that any legal copyright form needs to contain a list of all the software involved.

Obviously, I've used Adobe software, but plenty of other software too. I don't really see that as any of the client's business. Surely it has no relevance to the copyright of the final video, any more than the type of pencil I used to draw the characters - or the light bulb I used to see the sketch pad.

Do I need to declare what software I've used, just to transfer copyright of the final video over to my client?
