Yes, it is - I just looked it up on Wikipedia, which says
‘The lyrics of the song are often changed depending on the recording artist. In its original form it is a humorous romantic duet, though rarely recorded that way. Certain lyrics, especially those with topical references, are often changed based on the time of the performance's release’
I’d looked it up on ApplePlay, which gives you the official version, but Nicenanny3 could well have been referring to a version with altered lyrics. Mystery could be solved, thanks, unless she comes back to say it’s a different song she was referring to.
