Any link to this great source. At least Duke's popularity still remains. I would doubt anyone under 30 could tell you who Gable and Crosby were.

To be honest Mike I doubt if many people under the age of 30 know who John Wayne was. Last year I was speaking to some teenage girls and they had absolutely no idea who I meant when I mentioned his name. My own best friend at school had never heard of him until we watched "The Searchers" one Christmas.
