[Riverwolf]

Wasn't sure how to word this question, so here goes...
I was watching youtube videos of the Johnny Cash version of the song "Hurt"
Everybody agreed on all the chords and strumming except for variations of the F chord.
Except justinguitar who showed to slide an open C major chord up 1 step or 2 frets in place of the normal open D major chord.
While it's easy enough I'm not sold on the sound yet, still playing with it.
Anybody else use this chord?
I could not find it with a google search.
