Best song about New Orleans
Louis Armstrong "Do You Know What it Means to Miss New Orleans?"
Randy Newman, also done by Aaron Neville "Lousiana 1927"
Both of these are particularly meaningful following Katrina. I agree Fiyo, I can't listen to Louisiana 1927 without getting a tear in my eye. I taped the fundraiser that Harry Connick Jr. helped put on in the days after Katrina, and Aaron sang that song with so much emotion. I can't watch it without a few Kleenex.
But how can we forget the third song on my list: "Oh When the Saints Go Marchin' In"? No, it's not about New Orleans, but it does say "Saints" and that = New Orleans in my book. So there's my top three.
