GD: early 1971 logistical difficulties

I am sure there are more, but I am just putting down a marker to keep track of canceled/rescheduled/uncertain early '71 GD shows

• canceled (or maybe only tentatively planned?) shows on March 5-6 in New Haven, CT (Thomas 1970).
• show at Franklin & Marshall College reschedule from March 6 (busy day!) to April 10th (Weiner 1971). I thought I read somewhere that the GD claimed to F&M people that their entire March 1971 itinerary had been canceled, but now I can't find that information.
• canceled March 19, 1971 at the Syndrome in Chicago, as documented by Corry.
• uncertain April 2, 1971 show at Kent State, as discussed by Corry.
