santa claus song help - 70s or early 80s

My dad had an album from the 70s or early 80s. I think it was green with a young woman in a santa outfit standing backwards on the front. I'm specifically looking for the name of the group and this one song:

There's someone who's knocking at my door
The person keeps knocking more and more
The person keeps saying, "please let me in"
The one who is knocking is a man with a white beard on . .
....
.....
....
His name is Santa Claus

Thanks for any help you can give! This one has been bugging me for years. My parents divorced 10 years ago and the album was lost in the division of assets!

The song is "There's Someone Who's Knocking" by The Salsoul Orchestra.
