The Tony Hayes that I knew about definately lived in Hoo.(this would be the very early '80's) He is credited for co-writing "Black is Black" with Michelle Grainger and Steve Wadey. The song was a No.1 hit in 1966 for Los Bravos. It was later covered by a French Disco Girl Group La Belle Epoque in 1977 which reached No2 in the British Charts.
Hadn't looked at this thread for a while, but have a few additions to this post. I never met Tony Hayes but, while working for a short while as a draughtsman in Strood, a new draughtsman joined the firm called Steve Wadey. He told me he lived in Hoo and had co-written Black is Black and although I was dubious at first, we got to know each other well through a mutual interest in music. I was only 19 at the time and Steve had quite an influence on me over the months that we worked together, as he encouraged me to start my own business. He showed me how to set up a limited company and was a great believer in pushing yourself.
Steve was always telling me he was waiting for a royalty cheque from his publisher, which was why he was working as a draughtsman, and was going to start building multi track studio recorders as soon as the cheque arrived. One day he walked into the drawing office with a big smile on his face, saying he had received a cheque for South American royalties for £30000 and was immediately handing in his notice. I did wonder whether it was Steve who bought out Tony Hayes, as he was a shrewd guy.
I kept loose contact with him for a few years, and sure enough, he started a company called 'Cadey' which produced early multi track studio recorders. It became quite successful and in the early 1980s, I actually came by one of his recorders for my own studio? I believe Steve moved to Australia where he carried on with a successful business, but I have no idea what he is doing now.
