Thanks for doing this, very interesting.
You might want to add, as a note or otherwise, the "Laverne & Shirley & Company" change made for syndicated airings. A lot of us remember that, along with "Happy Days Again." (I don't recall though for L & S if it was "and" or ampersand "&" -- maybe someone has uploaded the lettering somewhere.) Were there variations of those syndicated openings as well?
