Background: Hooker's date of birth is a subject of debate; the years 1912, 1915, 1917, 1920, and 1923 have been suggested. Most sources give 1917, though at times Hooker stated he was born in 1920. Information in the 1920 and 1930 censuses indicates that he was born in 1912. In 2017, a series of events took place to celebrate the purported centenary of his birth.
Context: Beginning in 1962, Hooker gained greater exposure when toured Europe in the annual American Folk Blues Festival. His "Dimples" became a successful single on the UK Singles Charts in 1964, eight years after its first US release. Hooker began to perform and record with rock musicians. One of his earliest collaborations was with British blues rock band the Groundhogs. In 1970, he recorded the joint album Hooker 'n Heat, with the American blues and boogie rock group Canned Heat, whose repertoire included adaptations of Hooker songs. It became the first of Hooker's albums to reach the Billboard charts, peaking at number 78 on the Billboard 200. Other collaboration albums soon followed, including Endless Boogie (1971) and Never Get Out of These Blues Alive (1972), which included Steve Miller, Elvin Bishop, Van Morrison, and others.  Hooker appeared in the 1980 film The Blues Brothers. He performed "Boom Boom" in the role of a street musician. In 1989, he recorded the album The Healer with Carlos Santana, Bonnie Raitt, and others. The 1990s saw additional collaboration albums: Mr. Lucky (1991), Chill Out (1995), and Don't Look Back (1997) with Morrison, Santana, Los Lobos, and additional guest musicians. His re-recording of "Boom Boom" (the title track for his 1992 album) with guitarist Jimmie Vaughan became Hooker's highest charting single (number 16) in the UK. Come See About Me, a 2004 DVD, includes performances filmed between 1960 and 1994 and interviews with several of the musicians.  Hooker died in his sleep on June 21, 2001, in Los Altos, California. He is interred at the Chapel of the Chimes in Oakland, California. He was survived by eight children, 19 grandchildren, and numerous great-grandchildren.
