Most of my working life has been spent in the Biochemistry laboratory at Northwick Park Hospital, Harrow. After a few years I got bored writing "Best wishes for the future" every time a leaving or birthday card came round, so I started writing tailor-made individual poems. Most of these are hilarious, (especially if you know the person concerned) some are tongue-in-cheek, and some have turned into songs. Explanations of obscure references and tunes are available upon request. Tony Walker Biomedical scientist
