Imagine begins with Lennon and Ono strolling through a garden or forest. Then they come upon Lennon's London home, Tittenhurst Park. As they walk to the front door, they enter the house by disappearing outside and appearing inside. The camera pans up to see a window with the line inscribed "This is not here." The rest of the video consists primarily of Lennon playing on a white grand piano, in a white room, with a couple of white over-sized balloons. During the video Ono opens all the shades and watches Lennon play.
Dolly Parton's Version
Imagine features Dolly signing the song inside a house alongside with a man playing the piano.
