The album is also notable for containing a relative variety of song types – rock and roll ("Bad Bad Dreams"), power ballads ("Alive"), choral performances ("Please Don't Turn Out the Lights"), bizarre and psychedelic songs ("Paper Mache, Cabbages and Kings", "Sweet Song of Summer") and nostalgic love songs ("Sea of Smiling Faces"). The band never showed approval to the album, but for many fans it is an unusually authentic Bee Gees collection, closer in spirit to what the brothers found interesting to do than what they thought they owed the public. In the 2010 documentary In Our Own Time, Maurice was shown explaining (in archival footage) that by 1972 they didn't really know who their audience was, hence the title To Whom It May Concern.
