Some milestones in the history of civilization:
1772 BC: The Code of Hammurabi
1215 AD: The Magna Carta
1789: The Constitution of the United States
1793: The Declaration of the Rights of Man and Citizen
1863: The Emancipation Proclamation
1973: Ballroom Blitz
The Sweet actually was quite popular, as Wikipedia notes below. Two of the four original members have passed away.
The band achieved notable success in the UK charts, with thirteen Top 20 hits during the 1970s alone, with “Block Buster!” (1973) topping the chart, followed by three consecutive number two hits in “Hell Raiser” (1973), “The Ballroom Blitz” (1973) and “Teenage Rampage” (1974). The band turned to more Hard Rock style with their mid-career singles like 1974’s Turn It Down. Their first self-written and produced single “Fox on the Run” (1975) also reached number two on the UK charts. These results were topped in West Germany and other countries on the European mainland, where the band was very popular.
Two versions of The Sweet — each led by a surviving original member — carry on today.
