I went to the Budd Theatre as a child. My grandparents lived in Harrison. I saw Puff the Magic Dragon there. I dont remember what year that movie was made. I also saw the movie Grease there when that came out in 78. I think it was a small theatre maybe seated 100 or less people. It was on M-61 right in the town of Harrison. I am not sure when it opened but it closed I believe in the mid to late 80s.
Doing some detective work, I found the recent street view photo of the "theater hall" is in fact the old Budd Theater. Seth Landon indicated it was once the location of Mid Michigan Community Action. Doing some checking I found that organization did indeed use this address.
