My two cents worth——Steve Allen was the best.
Whoa...now that's dating yourself!
I remember Steve Allen, and liked him a lot. He sure could crack himself up, couldn't he? Funny guy. He made everyone smile.
Steve was early TV, though, and didn't quite master the late night talk TV groove as well as Johnny did. Johnny became an American institution, and in his time, was one of the most influential people in the entertainment business.
