About the same time as the first time i went i used the Eclipse as the subject for a college project i was doing at the time. This involved getting the train to Coventry, meeting Stuart Reid and getting a tour around the venue during the afternoon - quite an eye opener!
The official capacity was 1600. The busiest night i witnessed was an Amnesia night in July 1991 (my house is your house). According to one of the doormen 2200 had come through the doors.
