Love Song for Ron and Hermione??

[David Hardenbrook]

There's a song that I've heard in the supermarket muzak several times 
now.  It's a romantic-sounding mid-tempo number, and when I hear it, I 
always imagine Ron and Hermione dancing to it.  (Which is why I'm 
posting this request on this forum.)  The thing is, I can't identify 
the song in order to find a recording.  It sounds like the refrain 
is, "It's sweet love, it's sweet."  But a Google search turns up only a 
about a "googol" (pun intended) songs that contain those words, none of 
which I can find is right.

Can anyone assist me in indentifying this potential (to my mind) "love 
song for Ron and Hermione"?  The clues I have:

-- Song is mid-tempo, possibly a ballad
-- Lead singer sounds like a female soprano
-- Music style sounds 70's/ABBA-esque, though this is a guess on my part
-- Refrain at least *sounds* like, "It's sweet love, it's swee-eet."

Can anyone help?  If I have to, I'll post an Mp3 of myself humming the 
melody...
