(Mostly) music for this historic Inauguration Day of America's first African-American President Barack Obama!

At this time, I was interrupted by MIT Facilities workers who I had called in to correct a serious problem that they had recently caused with the ventilation system that supplies air to the radio station. Fumes were coming through the ventilation system instead of air, and the temperature was close to ninety degrees. If I hadn't been able to get MIT Facilities workers to the station to deal with the problem, I would have signed the station off the air and gone home instead of doing the show. Needing to play a long piece of music while I spent time over in a ventilation and boiler room showing the problem to the workers, I threw on this long Grateful Dead jam from the 1969 "Live Dead" album:

The ventilation problem now (sort of) corrected, and once again having some air to breathe in the studio, I continued the show as the temperature inside the radio station slowly lowered from about ninety to approximately seventy-five degrees.
