I know I'm just a tad bit tardy here, hehe.
Tom does have three kiddos, but those aren't their initials. ;-)
I thought Ed might have once said what K+D+B stood for, but either that was on the old forum or was in an interview. Or I could be mistaken. Otherwise I'd like to think I'd remember something like that. Then again, my memory does tend not to serve me as correctly or as often these days!!
Be kind, for everyone you meet is fighting a hard battle.
