From This Might Be A Wiki
Great show, the brass section in the encores was awesome! The call from the dead was actually from Carl Sagan, not his "brother" Richard Milhous. Carl did mention that his brother was buried next door and was trying to get out of his coffin. Carl Sagan also appeared later in the show in modified lyrics to Particle Man. The brave, dead TV astronomer tried to actually take down the mighty Triangle Man.
