What time do shows usually end if they start at 7?

Depends on how many bands there are, and how many songs they each play, e.g: lost80slive has 8 bands per show, and most play 3 songs except the main band which does a standard set (~8). At about 5 mins per song, plus intermission, the show ends btwn 11 & 12pm

Friday night's 80s concert ended at 10:30

9:30 -10pm

9:30 or 10:00...
