I've received dozens of e-mails from folks who are sure they've seen Tony Bennett perform "I Left My Heart in San Francisco" on TV since 1962. A couple even recall seeing him sing it on The Tonight Show With Jay Leno before last night and there are even online videos of him doing so. Here's a clip of him singing it on the Don Imus show on MSNBC one month ago. So I don't know what that business was about him doing it on TV for the first time in more than forty years.
