Covert Café

The sources disagree on the night.

A comedy listing site's detailed calendar for this venue shows a differently named, differently formatted comedy show with limited sign-up on some Saturdays, roughly monthly, but not a 4 PM music open mic [s1]. Since that listing only covers comedy, its silence about a music event is not strong evidence either way; the claim of a music open mic here rests on an open-mic listing site alone.
