A cover of blues legend Howlin Wolf’s song co-written by Willie Dixon. Back then a blues cover (especially of Howlin Wolf, Muddy Waters or anything written by Dixon) was as obligatory and ubiquitous a formula as you would have in the 60s (this is also one of those rare incidences that a original writer(s) were credited and compensated) this has somewhat dwindled since then.

The Doors often opened their concerts with this song.
