It is very inspiring to see a man doing what he did as far back as the '50's. He seemed to be doing very well with a nice song about solving problems without violence. David Letterman has been very considerate to many greta performers who are still with us. Recently he had Little Anthony and The Imperials perform a great song with a big orchestra and it sounded as good as the original.
David Letterman seems to be a great man.

I done did see that.

Great performance.
