I saw that when she posted it on Facebook -- very nicely done. (Most of the B7 filks are to tunes I don't know, so I think of them as original songs; it's odd when I occasionally encounter one on the radio with its proper lyrics, because it feels as if someone is unexpectedly filking 'our' music!)

I suggested she should try "It's Lonely When You Never See the Sky", but she pointed out that it might be a bit tricky to do a video for that one, as the protagonist is a pre-Way-Back character who never appears on screen in canon :-D
