November 14, 1993 saw ECW (then still NWA Eastern Championship Wrestling) participate in a "supershow" in Eassex Maryland. The event took place at Kenwood High School Gym.
Three promotions combined to make a "supercard": ECW, Mid Eastern Wrestling Federation (MEWF), and ASWA (All-South Wrestling Alliance). The main event from that night saw Jake Roberts take on Mr. Hughes (video above found on YouTube).
Several title changes took place that night, especially for the MEWF and ASWA roster members. Some of the wrestlers are considered ECW "alumni", and some aren't considered alumni due to whether or not this event was considered mainly an "ECW" show. For now, they are considered as such with that caveat as it is unknown who paid and promoted the event at this time.
Here are recaps of the card from that night:

Madusa also was scheduled to face Sherri Martell at the same show, and had a lengthy ECW Hardcore TV interview segment to promote the match; but that match didn't take place with Malia Hosaka replacing Madusa:
