[xmonad] mpc output in xmobar

[jean bonhomme]

Hello,
I would like to pipe this command :
echo -n "$(mpc --format "%file%" | head -n 1)"
to xmobar.
I haven't found any infos on how to do it.
I've tried severals methods but without any success.
On my best test, I could see the output in ~/.xsession-errors, but that wasn't my goal.
When someone knows how to do it, please let me know.
