Come to think of it here is an even more simple couplet, from a Leadbelly song which has almost mystic power in the right context because it invites so much from the imagination:

Redbird, redbird, singin in the mornin' redbird!
Redbird redbird, singin' in the mornin', redbird!

And another, which Leadbelly I think brought forward from friends on the prison gangs:

Ol' Reilly crossed the water
On them long hot summer days...

From "Here, Rattler Here". The latent imagery of the simplicity is amazing.
