What was the name of AC/DC's lead singer who died in 1980?

Ronald Belford "Bon" Scott (9 July 1946 – 19 February 1980) was an Australian singer and songwriter, best known for being the lead vocalist and lyricist of the Australian hard rock band AC/DC from 1974 until his death in 1980.

AC/DC's popularity grew throughout the 1970s, initially in Australia, and then internationally. Their 1979 album Highway to Hell reached the top twenty in the United States, and the band seemed on the verge of a commercial breakthrough. However, on 19 February 1980, Scott died after a night out in London. AC/DC briefly considered disbanding, but the group recruited vocalist Brian Johnson of the British glam rock band Geordie. AC/DC's subsequent album, Back in Black, was released only five months later, and was a tribute to Scott. It went on to become the second best-selling album in history.

In the July 2004 issue of Classic Rock, Scott was rated as number one in a list of the "100 Greatest Frontmen Of All Time" ahead of Freddie Mercury and Robert Plant. Hit Parader ranked Scott as fifth on their 2006 list of the 100 Greatest Heavy Metal Vocalists of all time. Because of his strong vocal range, lyrics, and personality, Scott is considered by many to be one of the most iconic, influential, and greatest frontmen of all time.
