There was an old Christmas 80's cassette tape that I have been looking for forever. It is about Santa's elves who are helping with Christmas. At one point, it start snowing and we learn that each snowflake is an elf. Anyone?

There was an 80's Christmas tape, possibly a book on tape... It was adventures of some elves who were helping with Christmas. At one point we learn that all snowflakes are different, because they are all elves. I think there was also a story on it about a Christmas tree that no one wanted. Thanks !
