David Letterman - 'My Next Guest Needs No Introduction'

The standup and late night comedy legend, who rarely grants interviews, opens up about why he pursued a public life despite immense shyness, why he adored Johnny Carson and has mixed feelings about Jay Leno, why he retired from 'Late Show' only to return two years later with a longform interview series on Netflix, what he thinks of today's late night hosts and how he feels now about his former frequent guest Donald Trump.
