Last summer I visited Louis Armstrong's home in Corona, Queens NY. If you're anywhere in the vicinity I recommend you take the tour. I came away with a much magnified view of Louis and Lucille at home and a box of Swiss Kriss. I haven't tried it yet. If you can't go, do go to this site. It's the best on Louis. Just added is an online catalog, skillions of fabulous photos.
