I bought this one only for one song, Pressed Rat and Warthog.  I already had Cream's first album Fresh Cream, and a best of album, The Very Best of Cream.  Pressed Rat and Warthog is unusual in that the "singing" is a vocal recitative, done in the usual deadpan British vocal style.  The British deadpan vocal style can be found, e.g., on any album by the Gang of Four, almost anything by Squeeze, for example, Up The Junction, and in Keith Relf's work with the Yardbirds.
