This painting was completed towards the end of Hockney's second year at the Royal College of Art at a time when homosexuality was still illegal in England. The painting derives its imagery from a poem of the same title by the nineteenth-century American writer, Walt Whitman: two lines of the poem have been scribbled on the right-hand side to offer a commentary on the men's activities. The painting also references a newspaper clipping detailing a climbing accident ('Two Boys Cling to Cliff all Night'), which Hockney interpreted as an allusion to his idol, Cliff Richard.
The two protagonists in this painting are seen exchanging a passionate embrace and kiss in front of a lavatory wall covered in grafitti. The use of an untutored or child-like style was suggested to Hockney by the work of the French artist Jean Dubuffet. Like the graffiti, this style gives the painting a crudity and vigour but also shrouds the identity of the artist in mock-anonymity.
