What was the first college production of Into the Woods?

Hi! I produced Into the Woods in April 1991 for Ram's Head Theatrical Society at Stanford University. We worked with MTI to secure the rights beginning in summer of 1990. We had to wait to finalize them because the bus-and-truck production was still touring, and we had to make sure they wouldn't be in our area. For years, we've been wondering if we were the first college production of Into the Woods? Can we claim that or did another school beat us to the punch? Would your records be able to tell us? Thanks for any help you can give!
