Mystery Song?

[sparch]

Dear friends,

For the last couple of weeks or so I have had this song in my head and I cannot, for the life of me, remember either the title or the artist. It's been driving me up the wall!

I obviously can't sing or even hum it to you, but I know some of the lyrics and they go something like this :

"I don't know why you are doing this ....."
"you are the angel I adore ...."
"nobody knows how much I care ...., you are my one and only love"
"you are the one who'll understand ...., the misery I'm going through"

and the refrain goes something like this :

"your love, your love is so sweet and that's what I really need"
"your kiss is like it used to be, your tenderness is what I need"

or words to that effect and not necessarily in this order! Where the dots are, a (probably) female soprano voice comes in with "ah-ah-ah's" and this is the striking part of the song.

I believe it is from the early 70's (1971 or 1972 would be my best guess) and the singer is male but it could be by a group and not a solo artist.

I tried searching in dozens of sites with lyrics-search engines, but to no avail.

Any help or ideas would be greatly appreciated. If I remember any more telltale info about it, I will be in touch again.

Regards, Simon.
