What band got it's name from a book by author William Henry Davies?

The band that got its name from a book by William Henry Davies was Supertramp. The title came from Davies's 1908 autobiography, The Autobiography of a Super-Tramp.

Davies was a Welsh poet and writer who spent years traveling as a tramp or hobo in Britain, Canada, and the United States. His book describes that wandering life and helped establish him as a distinctive literary voice. The word "super-tramp" was therefore a literary reference before it became the name of a rock group.

Richard Palmer-James, an early guitarist and lyricist associated with the band, suggested the name after reading Davies's book. Supertramp formed in London in 1969, initially with Rick Davies and Roger Hodgson at its creative center. The group became internationally successful after Crime of the Century in 1974 and later released the major-selling album Breakfast in America in 1979. The band name is not a reference to the later film or book Into the Wild, although that story also used the name "Alexander Supertramp."
