In 1970, which group had a UK No. 1 single with "Voodoo Chile"?

James Marshall "Jimi" Hendrix (born Johnny Allen Hendrix; November 27, 1942 – September 18, 1970) was an American musician, singer, and songwriter. Although his mainstream career spanned only four years, he is widely regarded as one of the most influential electric guitarists in the history of popular music, and one of the most celebrated musicians of the 20th century.

"Voodoo Chile" is a song written by Jimi Hendrix and recorded in 1968 for the third Jimi Hendrix Experience album "Electric Ladyland". It is based on the Muddy Waters blues song "Rollin' Stone", but with original lyrics and music. At 15 minutes, it is Hendrix's longest studio recording and features additional musicians in what has been described as a studio jam.

"Voodoo Chile" was recorded at the Record Plant in New York City, after a late night jam session with Hendrix, Experience drummer Mitch Mitchell, organist Steve Winwood, and bassist Jack Casady. The song became the basis for "Voodoo Child (Slight Return)", recorded by the Experience the next day and one of Hendrix's best-known songs.

"Chile" is a phonetic approximation of "child" without the "d". In the UK, "Voodoo Chile" was also used as the title of the 1970 single release of "Voodoo Child (Slight Return)", which has caused confusion regarding the two songs. The song reached No. 1 in the UK in November 1970.
