No - you are entirely logical. Don't we have an Landover show that we can compare screens to? Or am I thinking of a Bruce show there - damn let me check my list and get back to you here.

Yes - there is a Largo, Maryland show 1989-07-11 that we can look at and see if the screens are the same. 1993 is only 4 years later. People use such weird names for this venue, Largo is Landover in Maryland - or Capital Center. It's all the same place. From wikipedia:

The Capital Centre was an indoor arena located in Landover, Maryland,unincorporated Prince George's County, Maryland; a suburb of Washington, D.C. Completed in 1973, the arena sat 18,756 for basketball and 18,130 for hockey.

In 1993, the air carrier USAir purchased the naming rights for the building and the arena became known as USAir Arena. After the airline rebranded itself in 1996, the name changed to US Airways Arena. The arena reverted to its original name of Capital Centre after the airline dropped its naming rights and its primary tenants moved to the MCI Center (now named the Verizon Center) in downtown Washington. Most TV and Radio crews broadcasting from the venue referred to it by its nickname "Cap Centre". The venue's name is also sometimes misspelled as Capital Center, Capitol Center, Capitol Center Arena or Capital Center Arena. The venue was demolished in 2002.

Largo is an unincorporated area and census designated place in Prince George's County, Maryland, in the United States.[1] The population was 10,709 at the 2010 census.[2]

Let me dig out my discs and do some comparing The 89 show is stage shot so the screens may not be visible unless there is a long audience shot.
