Laindon High Road School. Believe picture dates to 1963 ?
Geoffrey Schroeder, John Kingsley, Jo Borowski among the “boys”
Valerie Boatwright and Denise Allen the only “girls” I can identify.
Unsure as to the teachers name, was this Mr. Durrant? Mr. Bear?
p.s. Valerie and Denise were almost conjoined twins, they were that close !
Editor: The teacher is definitely Mr Bear.
