I sailed with Mad Mac when he was Mate and Master in Stricks and he certainly was a character! I am not surprised you found some unknown 'gems' in your hometown. He used to reminisce fondly of his RNR time and HMS Bermuda and when on our ships often used to be go all RN which I was told was the exact opposite of Bill in the RN.
His standard cry when more staid counsel suggested he curb his enthusiasm was " Well they can only give me the sack!" I suspect he survived because when required he could produce the goods and some of his schemes actually worked. Never a dull moment when he was around!
