If I was guessing, I would assume this rose is a descendent of 'Yellow Pages' and one of Jack Christensen's proprietary yellow floribunda seedlings. The tip off, I think, is the dominant 'Arthur Bell' foliage type that seems to follow its hybrids for a few generations.

I see the problem with some of the references and photos. The older 'Golden Wedding' has photos of this 'Golden Wedding', and a reference here has the parentage of the older 'Golden Wedding' as this 'Golden Wedding'. So these two roses have been mixed up far before HMF.
