AMERICAN MASTERS on PBS recently presented "Tony Bennett: The Music Never Ends," produced by and featuring Clint Eastwood. It's pretty good. Bennett is not my favorite singer, stylistically, his bel canto is a bit old-fashioned, and he never could swing the way Sinatra did. But he's pretty much the last of his generation now.
Perhaps the most interesting thing in the doc is seeing Alec Baldwin doing Tony on SNL. His impression is frigging amazing. They did the hair and nose makeup perfectly, and Baldwin does his voice and moves perfectly. It's eerie.
