It's clear from the photos, including some not posted here that the EDL were being served drinks by The Harley, they tweeted:

"The venue was caught off guard, the police cleared our venue for us, and we are now closed until further notice."

And retweeted:

"@harleysheffield is one of the nicest, most welcoming places i've ever had the pleasure of going to a gig/eating/drinking. fuck the EDL man."

The EDL clearly got a better reception at other pubs in Sheffield, especially the Wetherspoon ones. If the EDL ever plan to return it would make sense to run a campaign in advance to encourage pubs to refuse entry to the EDL, after all who would want to drink in a pub that serves them?
