Most of Janis Joplin’s hits were reworked blues songs, often re-arranged to the point where the original song was barely recognizable. That’s pretty much the case with the Bee Gees’ “To Love Somebody,” which Joplin covered for 1969’s “I Got Dem Ol’ Kozmic Blues Again Mama!” LP and performed live on the Dick Cavett show. This is easily the most often covered song in the Bee Gees catalog, by everyone from Lulu to Gram Parsons and the Flying Burrito Brothers, but nobody, not even the Bee Gees themselves, has ever done it like this.
Barry and Robin Gibb composed the song at the suggestion of manager Robert Stigwood, who wanted them to write something for Otis Redding to record. Redding died in a plane crash before he could record the song, so the Bee Gees did it themselves. Decades later, Barry Gibb declared it his favorite of the score of hit records he wrote or co-wrote. Barry was no Otis Redding, but the brothers’ harmonies make up for the relative lack of soul.
