The Mercy Seat chords & tabs

Nick Cave - Mercy Seat
I was reading the tabs on this site and came up with this alternative.
The verse is Em and Bm but I think the song is the Em bar chord on fret 7 5th string and 
fret 7 barred accross from the 5th string like this:
--7---7--|
--8---7--|
--9---7--|
--9---7--|
--7---7--|
---------|

This doesn't apply to the verse which I use all bar chords for. The guitar chords in the 
Nick Cave recording are just strung once and let ring with a whole bunch echoe and 
droney stuff.

Em         Bm
