It aint Don Williams!!!?

Name that song and who done it!!!

now sometimes grownups grow up to believe
that you don't really come on Christmas Eve
but I don't think that's true
'cause I know I see you

I didn't know Ronnie Milsap sang it also. I am only familiar with Alabama and Andy Williams versions of this song. I am going to look for Ronnie version, he has such a great voice!!!!
