For a project that I may have coming up, I wanted to define a dozen iconic song performances in the “American Songbook” style. That way, if teaching for example, one can say, “Could you give it a little more Peggy Lee cool?” and someone might know what you’re talking about. I’ve tried to limit it to the root of a style, so we have Sinatra but no Tony Bennett, Louis Armstrong so no Louis Prima, etc. And I restricted it to performances that were available on YouTube because I belive you have to watch performances, not just hear vocals. Looking forward to comments about people who are questionable on the list and who has been unfairly disregarded.
