Since Loni has the name recognition, Bob may very well be viewed as "Mr. Loni Anderson.
(I think I could live with it....)

But while Bob Flick is a name known to fewer people, those of us who recognize the name also recognize the man's accomplishments. Had he wanted status and recognition beyond what he had over the past 40 years, he surely would have gone after it and achieved it.

I would bet he's satisfied and secure in those accomplishments and isn't threatened by Loni's greater fame. Moreover, they're adding marriage to a friendship they must have maintained all those years. Congratulations and success to their union and God bless them both!
