Question: Derek Hough and Joe Strummer, have which mutual occupations?

Context paragraphs:
The Joe Strummer Foundation: The Joe Strummer Foundation is a non-profit organisation which promotes the development of new music.  It was established in memory of punk rock singer and guitarist Joe Strummer shortly after his death in December 2002.  Strummer's widow Lucinda was the principal founder along with their daughters, Jazz and Lola Mellor, and English artist Damien Hirst.  The organisation was known as Strummerville until December 2014.

Bernard Rhodes: Bernard Rhodes is a fashion designer, record producer, songwriter, manager and impresario who was integral to the development of the punk rock scene in the United Kingdom during the middle 1970s.  He is most associated with two of the UK's best known punk bands, the Sex Pistols and The Clash.  It was Rhodes who was responsible for discovering John Lydon and arranging the audition in the King's Road for him to join the Sex Pistols.  He also introduced a young Mick Jones and Paul Simonon to Joe Strummer and together with Keith Levene they formed The Clash.  Rhodes was an important force behind The Clash, not only managing their business, but also handling marketing and creative direction of the band.  He left the band from 1979 to 1981 to pursue other opportunities, but tensions in the band led to singer-guitarist Joe Strummer demanding (and getting) his return in 1981.

Derek Hough: Derek Hough ( ; born May 17, 1985) is an American professional Latin and ballroom dancer, choreographer, actor and singer.

Elgin Avenue Breakdown: Elgin Avenue Breakdown is a compilation album by The 101ers, Joe Strummer's band before he joined The Clash.  It was released on Andalucía Records (distributed by Virgin) in 1981 because of The Clash's popularity but mooted at the time that it was a semi-unofficial release due to Joe Strummer's contractual obligations with CBS.  The first 500 copies came with a free poster.  Just a few thousand copies were sold.  The re-issue by EMI in 2005 has an accompanying booklet with an overview by Allan Jones and detailed notes on each track by Richard Dudanski.

Lost in the Supermarket: "Lost in the Supermarket" is a 1979 song by the Clash.  Written by Joe Strummer and Mick Jones and produced by Guy Stevens, it is credited to the Strummer/Jones songwriting partnership.  It was released on their third studio album "London Calling".  It is the eighth song on the track listing.  Although it features Mick Jones on lead vocals, the song was written by Joe Strummer.  The supermarket in question was the International, located at 471-473 Kings Road, beneath the World's End Estate.  31 Whistler Walk was where Strummer lived at the time with his girlfriend Gaby Salter, her two younger brothers and her mother.

Redemption Song: The Ballad of Joe Strummer: Redemption Song: The Ballad of Joe Strummer, originally published in different form in the United Kingdom in 2006 by HarperCollins as Redemption Song: The Authorised Biography of Joe Strummer, is a biographic book by Chris Salewicz released in May 2007.  The book documents the life and death of Joe Strummer, the front man of The Clash.  Apart from going through the history of the band, the book also goes into deep descriptions of Strummer's relationships with his friends and family; including how his brother's suicide influenced him.

Streetcore: Streetcore is the third and final studio album by Joe Strummer & the Mescaleros.  The album was completed after the death of frontman Joe Strummer, primarily by Martin Slattery and Scott Shields, and released on 21 October 2003.  The album marks the band's transition from their previous genre-bending work to a more straightforward rock album, reminiscent of Strummer's early work with The Clash.  The album received a positive critical reception and is generally seen as a return to form and a high point for Strummer to have gone out on.

The Latino Rockabilly War: "The Latino Rockabilly War" was a band most notable for backing The Clash frontman Joe Strummer on one album.  With Strummer, the Latino Rockabilly War created the album "Earthquake Weather", released through Epic Records.  The album was well received by critics, but did not sell well and Joe Strummer lost his deal with Epic (excepting a hypothetical circumstance in which he decided to reform or re-create the Clash with the same or new musicians, in which case he would have been forced to work with Epic).  Led by Strummer, they also contributed five songs to the soundtrack for the movie "Permanent Record", which featured a young Keanu Reeves: "Trash City", "Baby the Trans", "Nothin' 'bout Nothin", "Nefertiti Rock", and the instrumental "Theme from Permanent Record".

Joe Strummer: John Graham Mellor (21 August 1952 – 22 December 2002), known by his stage name Joe Strummer, was an English musician, singer, actor and songwriter who was the co-founder, lyricist, rhythm guitarist and lead vocalist of the Clash, a punk rock band formed in 1976 as part of the original wave of British punk.

Global a Go-Go: Global a Go-Go is the second album by Joe Strummer and The Mescaleros, displaying trademark genre-melding folk-rock and Strummer's unique lyrical style.  As the title suggests, there are world music influences on the album, mostly on the title track and "Bhindhi Bhagee", a celebration of the "humble" but diverse and exciting ethnic and multi-cultural areas of London and other major cities.  The album is heavy on acoustic instruments, especially in the instrumental "Minstrel Boy", a nearly 18-minute-long arrangement of a traditional Irish song.  Other topics covered include Strummer's radio show, which was broadcast on the BBC World Service ("Global a Go-Go") and left-wing political issues Strummer was well known for expounding as a member of The Clash.  The album was well received by critics and fans, making much more of an impact than the group's previous effort "Rock Art and the X-Ray Style".  The title track, "Global A Go-Go", features backing vocals from longtime friend of Strummer, Roger Daltrey.  Pete Townshend is also rumoured to be buried in the mix of "Minstrel Boy", but this has never been positively confirmed.  The cover-art for the album was designed by Josh Shoes and Strummer.
