I grew up with Ed Sullivan.....then came Johnny Carson.....then came Arsenio and Jay Leno. All greats.
Ed Sullivan introduced acts like the Beatles, Rolling Stones, etc.
Johnny Carson introduced people like Seinfield, etc...Jay Leno took over from Carson.
I am very saddened that he passed away. He was my favorite late night talk show host. When he retired then I switched to Letterman. I wish they would play reruns of the Tonight Show because those are priceless. He will be missed by many!
