INDEPENDENCE TOWNSHIP __ A Very Special Evening With Dave Matthews Band certainly lived up to its billing on Tuesday, July 7, at the DTE Energy Music Theatre, thanks to some very special guest performances.Blues Traveler's John Popper, who will be part of the H.O.R.D.E. festival show Thursday, July 9, at DTE, joined the DMB on stage for some killer harmonica on "What Would You Say" And The Lovely Ladies, a vocal trio that hasn't sung with the DMB since 2001, provided honey-sweet background vocals on "Everyday," a showstopper that had the crowd singing along in unison and swaying to the beat.
