The song playing in the background to this video of a velomobile, sung by Eddie Grant, titled "Electric Avenue" seems to be a very fitting theme song for electric vehicle enthusiasts.
Note that the velomobile in this video, an "Aurora" has an electric hub motor in it's front wheel. And this velomobile has pedals inside for human power as well.
And this along with other velomobiles, with and without electric power assist will be at the "Left Coast Velomobile Gathering" in San Louis Obispo on March 24-25, 2007. (video from 2006 gathering)
