The Jam were an English mod revival/punk rock band during the 1970s and early 1980s, which formed in 1972 at Sheerwater Secondary School in Woking, in the county of Surrey. The band released 18 consecutive Top 40 singles in the United Kingdom, from their debut in 1977 to their break-up in December 1982, including four number one hits. As of 2007, "That's Entertainment" and "Just Who Is the 5 O'Clock Hero?" remained the best-selling import singles of all time in the UK. They released one live album and six studio albums, the last of which, "The Gift", hit number one on the UK Albums Chart. When the group disbanded in 1982, their first 15 singles were re-released and all placed within the top 100.
