The Feathers in Laleham, Surrey, had displayed an advertisement stating that the establishment had music "from 4am" - 4am being the name of the band that were playing a gig there.
Four police officers barged into the pub, accusing the owners of not complying with public house rules, Orange News reports.
Licensee Kate Dillon said: "I was angry more than anything on the day. We've never had any need to call the police or had any trouble. When I calmed down a bit I thought it was absolutely hilarious. They made idiots of themselves really."
Dillon informed the officials that 4am was the name of the band and that they would be playing within normal hours.
A spokesperson for Spelthorne Borough Council said: "The visit was carried out following seeing an advertisement which mentioned 4am. On investigation, this was part of the name of the band."
The spokesperson went on to state that such visits are often made, with or without pre-arrangement, and it just so happens that The Feathers was on the visiting list that evening.
4am are made up of Joe Becket and John Adams, and are named after a song by jazz musician Herbie Hancock.
