Here are two different versions of Radiohead performing Creep, one of my favorite songs.
This one, from 1994, is aggressive and raw, but softened by Thom Yorke's emotional vocals. Note the absence of "fuck" in the chorus.
This one, from a live performance in 2006, is much more robotic and, in my opinion, mush less effective. Maybe it's the crowd that dulls it, or the fact that the band is 12 years older, or that they have performed this song too many times to count and they're just sick of it now. Even the inclusion of casual cussing doesn't help; it almost makes this version worse because even though all the ingredients for a hella-powerful performance are there, it just doesn't happen.
There's no point to this post, really, except as an excuse to listen to Radiohead, even not-so-good Radiohead.
