If you could scan the original there are on certain scanners (Epson D600 for example) there is a descreening button which i think would certainly help reduce the problem.

Thats because its not noise. Its the screening done when a picture is printed in a newspaper, magazine, yearbook...
You could try scanning it with the "de-screening" option checked in your software.

I am unable to imagine that. Could you expand on how you use the lasso tool to remove noise?

You have a halftone image. To have any chance of eliminating the dot pattern, you need to re-scan the image at a higher resolution, say between 600 and 2400 dpi. Your histogram for the image should have the blacks climbing the right wall, and the whites climbing the left wall. There will be little information across the center.
Once you have a good clear and sharp tiff file showing the dot pattern, it’s off to Photoshop or another pixel editor. First you need to blur the dots. Make copies of the background layer. Label them Gaussian Blur, Lens Blur, and Box Blur, and apply those filters. One layer will stand out as having the fewest dots. I then copy that layer and apply a dust and scratches filter followed by an Unsharp mask to help sharpen the image.
Good luck.

click on the lasso tool, and apply over the areas of digital noise or grains and go to edit-fill-choose "content aware" while choosing content option and then click"OK" and you need to do it several times over several areas. most of the time it works. this is my desperate attempt to remove digital noises and grains if all else fails.

The way it is as scanned, the noise (i.e. the dots) are bigger than the small detail you want to keep (facial features etc), so whatever you do to reduce the dots is guaranteed to reduce or even obliterate the small detail. One possibility is to use a brush or whatever to select the whole image and then erase the brush/mask from the areas where you don't want to lose detail (the faces mainly). Then you can apply fairly aggressive denoise to the rest of the image via the brush/selection.
The grain is so bad that the possibilities are very limited, and if at all possible you should do a re-scan. This is the best I could do with lots of tweaking and selecting as described above.

My attempt. So So at best.

My Epson V500 has a descreening option that will greatly reduce the printing screen pattern of dots you are seeing. You would do better by scanning the image rather than photographing it.

It wouldn't be noise if the kids would simply get their instruments in tune.
That's where my mind went.

Johnsnap ...Photoartist did a really great job with what he had to work with ,,,.
I have included what I could do as I’m on vacation in CALIF now and could only use my IPAD PRO .. vs my home operation and programs ...

It’s not “noise”, It’s the screen pattern from offset printing and it is not going anywhere. Anything you do to reduce the dots would be at the expense of overall sharpness.
I'll second that.
