"Rat Trap" is a single by The Boomtown Rats which reached No. 1 in the UK Singles Chart for two weeks in November 1978, the first single by a punk or new wave act to do so. It was written by Bob Geldof, and produced by Robert John "Mutt" Lange. It replaced "Summer Nights", a hit single for John Travolta and Olivia Newton-John from the soundtrack of Grease, at number one in the UK chart after the latter's seven-week reign.
