The singing or the bombing? Well, actually they're tied together.
When I was 15 I worked at Pacifica Radio in Houston, TX. I did comedy skits late night, news, etc... Pacifica, for those not familiar, especially back then, was a bit "liberal", or as my dad would tell me "a bunch of commies".
We were not popular with the Ku Klux Klan and they bombed our tower. Arlo Guthrie's record was playing when the station was bombed and we went off the air.
When we went back on the air many months later, the PBS show "Great American Dream Machine" did a documentary about us and had Arlo Guthrie come to the station to sing a song he wrote about the bombing. I was placed next to Arlo to "sing along" on the tv show (along with a group of station workers).
note - I found that the show has been archived in the Library of Congress. I have been immortalized.
