Same sort of thing goes on in all walks of life. Fighting over property - intellectual or otherwise after an acrimonious split. Why should music be any different?
One if my favorite lines of all time is sitting in a Texas divorce lawyer’s office. She says “In my cases someone is always fighting about who gets the black and white TV and the rhinestone encrusted douchebag.”
This was more than a few years ago of course.
I believe the divorce would be because one of the couple WAS a rhinestone encrusted douchebag.
