POP by Nightly: Halloween Edition This October 29, Gallery Club London gets a little less ordinary. Dress up, bring your people, and get ready for a night of commercial pop music, throwback anthems, guilty pleasures, and sing-alongs from start to finish. From the songs you know every word to the ones you forgot you loved, we're taking over the dancefloor for a Halloween party where the costumes are outrageous and the energy is unmatched. Your costume is your entrance statement. Your music taste is not up for discussion. Gallery Club London October 29 Commercial Pop & Anthems All Night Long
