I'm SO glad to have found this! Could not remember the whole thing! We sang it in school in NYC when I was a child in the 1940's. It might have been in a Concord Song Book full of translations of European folk songs. Ours had the line about Annette - not Nanette. "Ah my fair Annette, I bid you again good morrow. Ah so blue your eyes like the sky on a summer's day"
