"Mister Can't You See" is a song written by Mickey Newbury and Townes Van Zandt that first appeared on Newbury's 1968 debut album Harlequin Melodies.
Newbury's original version was slow and dominated by strings and a very simple drumbeat, with his voice telling a tale of nature's power and beauty.
The actual title of the song comes from the line "can't you see the river flowing".
