The singer courts an ugly woman on Duckworth Street. One night "I found her faithless she Fryin' sausages fer he." When he tells her "we must part ... With a fryin' pan she broke my head."
If "sometimes a cigar is just a cigar" maybe there is no double entendre here about frying sausages. On the contrary, this seems a song in which the writer let the metaphor get away. Peacock points out that Duckworth Street is one of the main commercial streets in St John's. - BS
