The paper version of Why Didn’t I Think Of It First – a book about crazy inventions patented over the years – was published in 1972 (ISBN 0 7153 5419 1 I ) and repurposed 2022 as an e-book using Jutoh 3 software courtesy of developer Julian Speed.
The WDITOIF e-book is posted here for free reading. Please no re-publication or repurposing, without a decent name-check credit.
The book illustrations, by the way, were done by Tony Hayes, the highly regarded singer, musician and arranger who co-led the Fraser Hayes Four tight harmony group – which you can still hear here, thanks to YouTube, performing on old episodes of Round the Horne and Beyond our Ken.
