Re: bar charts with error bars?

Hi.  This is a followup to my previous question (quoted below)

The idea provided by David of combining BarChart with
ErrorListPlot works fine for a single row of bars (thanks David!)
Anyone have any suggestions on what to do
for grouped bar charts, such as what you get with 

BarChart[{1,2,2,3},{2,3,3.5,4},
      BarLabels->{"Monday","Tuesday","Wednesday","Thursday"}]

It's not clear how to use ErrorListPlot here, since there
are multiple bars for each x value.

Any further suggestions would be very welcome. 

thanks,
