Walton was sent to a local school, but in 1912 his father saw a newspaper advertisement for probationer choristers at Christ Church Cathedral School in Oxford and applied for William to be admitted. The boy and his mother missed their intended train from Manchester to Oxford because Walton's father had spent the money for the fare in a local public house. Louisa Walton had to borrow the fares from a greengrocer. Although they arrived in Oxford after the entrance trials were over, Mrs Walton successfully pleaded for her son to be heard, and he was accepted.
