If it hasn't already been recced all over your f'list, stop what you're doing and go watch this
Ashes to Ashes/Life on Mars vid by
hollywoodgrrl. Seriously. Watch it. Watch it now.
And, to balance that out, here are two cracky A2A/LoM vid recs that I know you've seen but that you should watch again:
Bowie (Flight of the Conchords) by
fahrbotdrusilla -- Just the concept of making an A2A/LoM vid to this song is absolute genius.
There Is Too Much Light in this Bar" (Wammo) by
absolutedestiny -- STILL the best Life on Mars fanvid ever.
(I know
lifein1973 did a big vid rec thing a while back, but does anyone want to share with me their favourites?)
