I have been trying to locate a song that was my favorite when I was a young girl. I'm guessing it would have been around 1960-1964. My sisters thought it was Leslie Gore but I've been unable to find it on any of her albums. There was a song named "Danny" on the B side of "It's my Party", but when I heard a bit of it online it didn't sound like the same side. I remember the chorus very clearly. It was:

Danny, Danny, Danny, there's an ache in my heart
If you just knew
How I loved you
You'd love me too
Oooh ooh ooh ooh

Does anyone know what song this is and who sang it?
I would be very grateful.
