Lansing State Journal, 6 September 1990, page 9 What's On

PattonTrader and CV Database both list this gig as:
"September 8, 1990 Clarksteen (MI), Pine Of Music Theatre"

It's now believed this was a warping of the actual venue, "Pine Knob, Clarkston" on 7th September and so this date has been updated as such.
