"Rat Trap" was a single by The Boomtown Rats taken from their second album "Tonic For The Troops" and 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 "Summer Nights" seven week reign at the top. It is a rock ballad, telling the tale of a boy called Billy who feels the depressing town he lives in is a "Rat Trap". When the band performed the song on Top of the Pops (which is also mentioned in the song) as the UK new number one, the band members began by tearing up pictures of Travolta and Newton-John to emphasise the fact that the pair – who had spent a total of 16 weeks out of the preceding 22 at the top of the charts – had been deposed. Geldof mimed the saxophone part on a candelabra, a jest he explained in his autobiography Is That It?: "The Musicians' Union had forbidden me to play saxophone on the video, as obviously I hadn't done so on the record. But I saw a candelabra on the piano at the shoot and I put a mouthpiece in the central candle holder and played it. The impact of video came home when during the next few British gigs kids pulled out candelabras from nowhere and began playing them during the sax solo in 'Rat Trap'".
