In June 1984, bolstered by the instant massive success of the band's follow-up single ' Two Tribes', the single re-entered the Top Ten for a further nine weeks including two spent at number two (behind 'Two Tribes'). It remained in the UK Top 40 for 37 consecutive weeks, 35 of which overlapped with a radio airplay ban by the BBC (owing to lyrics perceived as overtly sexual). One of the decade's most controversial and most commercially successful records, 'Relax' eventually sold a reported two million copies in the UK alone, easily ranking among the ten biggest-selling singles ever. Three weeks later it reached number one, in the chart dated 28 January 1984, replacing Paul McCartney's ' Pipes of Peace'. The hit version, produced by Trevor Horn and featuring the band along with other musicians, entered the UK Top 75 singles chart in November 1983 but did not crack the Top 40 until early January 1984. ' Relax' is a song by English synth-pop band Frankie Goes to Hollywood, released in the United Kingdom by ZTT Records in 1983. Frankie Goes to Hollywood singles chronology
