80's "Saturday Night Live" Christmas skit????

Okay me and my sister used to watch SNL back in the 80's and every Christmas they would have this skit that involved these two women singers with big hair. They where really annoying singers all they sang were Christmas songs"here come the bells-Jingle-ling-ling" it was really funny. does anyone know what there names where on the show or what there group name was? or where can I find the skit so I can e-mail it to her. I already searched "You Tube" Please it would be much appreciated thanks!
