MissoulaEvents calls this Monday night 'Monday Underground,' billing it as 'the first ever comedy night at The Grotto.'
The Grotto
A Monday each month · 6 PM
Monthly on a Monday, 6:00 PM; no source says which week. The Venue's Website does not mention it.
Call to confirm the night
The sources disagree about whether it still runs.
The Venue's Website does not mention an open mic (checked Aug 14, 2026) [s2]. The only other event found at this venue was a single past comedy night on Jun 30, 2025 — a different genre than the listing site's music claim — raising the possibility the listing mistook a one-off event for a recurring series. This is not resolved.
