Mary lyrics

I saw Mary, she was walkin' on the water
Smiling at me, humming her river song
And I tried waving
But she was walking away
Said that she'd been waiting on me
All day long

I tried to call her
And said, "Please come back
Because I didn't mean to make you sad."
She said
"Well don't you worry
'cause I'll see you again
But I hear my mother callin'
And I have to go
