"Should you have met, quite by chance while down in Nassau, the composer, Charlie Lofthouse, you would find yourself chatting agreeably about tourists, about music, about fellow Bahamians and last, but certainly not least, his stories of four years of gay life in Paris. In these years he studied voice and classical music but not so intensely as to interfere with his existence in the Quarter Latin. He obviously became an expert writer of calypso music and moreover he knew how to have fun."

Is there a place I can read it for myself on the internet?

If this is the case it does make a stronger case for the claim made by Heilner, Van Campen in 1922 of the tune being a tune in Paris as you have stated.

However this doesn't prove it because even doe he copyrighted peas n rice in 1931, a song which has been documented since 1921 he never copyrighted the Ballymena, so if this was his song, why didn't he copyright it along with peas n rice?
