Spanish music help asap!?

In my Spanish 2 cl we have to sing a song in Spanish. A christmas Song. My group wants to do "I Saw Mommy Kissing Santa Claus" but we cant find the music to it. we need the instrumental of the Spainsh version. If we cant have that then we would like "Deck the Halls" or "Holly Jolly". Any thing will help. thanks!
