The Dave Matthews Band's concerns for the environment stretch from marine life in Biscayne National Park to transit riders in the San Francisco Bay Area.

But on Tuesday the band was accused of making a not-so-ecofriendly contribution to the Chicago River: dumping raw sewage from a tour bus onto the heads of people aboard an architectural tour boat.

A civil complaint by Illinois Attorney General Lisa Madigan says the Dave Matthews Band Inc. and Stefan A. Wohl, the driver of the bus, polluted the river by illegally dumping "liquid waste'' from the septic tank of the bus. Madigan said Wohl flicked a switch behind his seat and unleashed up to 800 pounds of human waste as he drove one of the band's buses over the Kinzie Street bridge.

Her office is seeking $60,000 in penalties.

The band -- which has sent investigators pictures of the buses and even offered to provide DNA samples to fight the allegations -- defended the driver.

"Our driver has stated that he was not involved in this incident,'' a statement from the band said. "We reserve judgment on anyone until we have seen the evidence. We have been and will continue to be cooperative in this investigation.''

not even spidey could have saved them poor people on the boat.
