Identify comedian's TV special in the late 1980s or early 1990s whose stage looked like the inside of his apartment

Please identify the comedian I saw on HBO or Showtime in the late 1980s or early 1990s whose stage looked like the inside of his apartment.

He was supposed to be home writing for work and kept getting sidetracked by other things. He was tall and thin and sang "Elvis has left the building".
