I almost forgot today's #filk #music ...my other top favourite:
Pushin' the Speed of Light by Julia Ecklar and Anne Prather.

The best way I can sum this story up is "The plight of the young working man, watching everyone else age into oblivion as he lives life aboard a relativistic starship." Very poignant.
I like to contrast it with '39 by Queen, which has a similar theme, but with the main characters being seen as heroes rather than everymen.
