2009 and Mrs B and I took a group of kids to Chicago. We took then up the Sears Tower, before ascending you had to watch a presentation about how it was built. Part of the show included adverts, one of which involved a young black child sneaking out of his house to visit jazz clubs. The child being a young Louis Armstrong. The lights came on and we filed out of the theatre to get the lifts upwards. As we walked out one yr 10 girl shouts to me "Hey Sir, Louis Armstrong, wasn't he the first man on the Moon"?
