Anyone know the album and artist's name for this song?

[Srikanth]

The song goes something like this : "Last Christmas I gave you my heart, But the very next day you gave it away...." .

I can't remember the artist and album's name. Anyone knows?

That's ol' George Michael.

 

[Srikanth]

And what about this song : "Nothings gonna change my love for you, You wanna know by now how much I love you..." ?
Is it from George Benson or somebody else?
