The Doris Mary Anne Kappelhoff Special

She only ever made two variety 'specials', this was the first and probably the best, some of the great old Doris Day standards as well as a few newer ones, Perry Como is as laid back as ever, a surprise guest and some very energetic dancing by Doris at 47, gotta say the 'Them Was the Good Old Days' number is my favourite albeit too short! Did anyone notice that the opening credits has her name spelt as Kapplehoff, every where else I've seen it including here, it's spelt Kappelhoff, I'm guessing the former is correct, You'd assume Doris would have known how to spell her own real name?
