Well, we sang Firefilk songs on the picket line and it went well!

Although, lemme tell ya... singing and walking and picketing all at the same time is mighty tiring. Cedric (of the Bedlam Bards) and I had our hands full. (Hawke and Joyce were both back at the hotel, being ill, poor Browncoats.) We found that the short one I wrote, based on the
Firefly theme song, worked better in general because it was shorter and easier for those around us who were singing along to remember. But we did both of them, and Cedric also did "Freedom Costs" - a march song he wrote for the 76th Battalion, I believe.
Anyhow, I've fiddled with both recordings a little, so that they sound a bit better. I wish we'd been able to get a recording of a group sing, but unfortunately, we didn't.

Here's the ME Day Theme:

When I gave a copy of the lyrics to Ben Edlund (who wrote the episode "Jaynestown" and the song "The Hero of Canton") he thought it was really neat. :) Tim Minear, who was standing nearby, nudged Ben and said in a low, joking voice, "Hey, you should sue 'em!" To which B!x said, "Well, if you decide to sue, remind me to not tell you which verse I wrote..."
Both of them are, of course, also uploaded to Can't Take the Sky Radio, a 24-hr Browncoat radio station at Live365. (It works best with Explorer, btw.)
