The Liverpool Poets published 'The Mersey Sound' in 1967, a collection of poems by Adrian Henri, Brian Patten, and Roger McGough. The anthology sold over 500,000 copies and launched their careers. It featured accessible poems using everyday language and symbols that resonated with 1960s counterculture. The poets sought to make poetry entertaining and part of the pop movement. They later formed a band called 'The Liverpool Scene' to perform their poems, though it achieved little commercial success. 'The Mersey Sound' had a profound impact on readers and is still widely influential today for its direct yet thoughtful depictions written in a lively style.
