Thanks Dani
And thanks Janet...appreciate the info. Whenever I'm doing older Nursoda characters, I usually use firefly, especially when testing things in the hair room since it's already a certain amount of resource load on the system. So far the green hair has been a random occurrence, and Linda indicated that she had the same thing happen. I was concerned that it might happen during the Beatles hair, and so I cut corners from what I'd normally do. I may try doing Paul's again.
When you google abbey road, hundreds of pictures show in the search results...about like with "grumpy cat" or "mona lisa", and some are interesting.
This is a better reference photo for their clothing:
