Lenny's was sad towards the end obviously but it was an awesome read. Dave Courtney's are good fun too.
I imagine there was some embellishment involved in these books, but Lenny was certainly a tough bloke.
I think on the cover of the book it says "I look what I am... a hard bastard!"
I remember in the days pre-YouTube I bought a DVD off of eBay of all his fights. Shit quality but very entertaining, moved well for a big man.
