Enjoyed the quiz! I've been trying several of yours. A couple of suggestions: 1) "its" harbor -- possessive pronoun, not abbreviation for "it is." 2) for Americans, please accept "theater." 3) Check spelling of "Mendelssohn," maybe allow a few misspellings. Also, Richard Wagner wrote a wedding march which is at least as famous as Mendelssohn's.
Thanks 'FentonsDad'....... have used a couple of your suggestions. I already had 8 different spellings of Mendelssohn on that question, you can't cater for everything, likewise I already had 6 different answers down for theatre but not theater. It is all good fun.
