At the age of 17, Boe became an apprentice mechanic at the TVR factory in Bispham, Blackpool. He enjoyed entertaining his colleagues by singing opera arias while he polished the cars, and one day was overheard by a client with connections in the music industry who was so impressed that he suggested Boe should go to London and audition for the D'Oyly Carte Opera Company. His audition was a success and he gave up polishing cars to embark on a singing career. Boe has not been able to trace the customer who suggested he go for the audition, having lost the man's business card.
