Last night, as David Letterman was doing a series of Cheney jokes, he mentioned that the guy Cheney shot had "a heart full of buckshot". He then turned to Paul and asked, "'A Heart Full of Buckshot' .... Isn't that an old Joni Mitchell song?"

Paul responded that he was thinking of the Yardbirds (Heart Full of Soul) to which Letterman just laughed and shrugged.
