Their first UK Top 10 hit, Culture Club’s Do You Really Want To Hurt Me reached number 1 in 1982 and also number 2 in the USA.
It really was a new and original sound and they went on to have great success, though only had one further number 1 (in 1983).
Note: Lead singer Boy George did actually have another UK Number 1 later on in the 80s with Everything I Own.
