Question: Nam Woo-hyun and Roy Wood, have which mutual occupation?
Context: Boulders is the first solo album by Roy Wood.  Apart from harmonium on track one played by John Kurlander, all the instruments (including guitars, cello, saxophones, recorders) and voices were by Wood, who also wrote, arranged, and produced the whole album, and did a self-portrait for the front cover.  Issued on Harvest, it peaked at No. 15 in the UK Albums Chart.  The album also peaked at 176 on the US Billboard 200. "Fire Brigade" is a song written by Roy Wood and performed by The Move, with Wood on lead vocal.  The song contains a guitar figure straight out of Duane Eddy.  Glen Matlock of the Sex Pistols admitted some years later that this guitar had strongly influenced him when they were writing their single, "God Save the Queen". Roy Wood (born 8 November 1947) is an English singer-songwriter and multi-instrumentalist.  He was particularly successful in the 1960s and 1970s as member and co-founder of the Move, Electric Light Orchestra and Wizzard.  As a songwriter, he contributed a number of hits to the repertoire of these bands. The Electric Light Orchestra (ELO) are an English rock band formed in Birmingham in 1970, by songwriters/multi-instrumentalists Jeff Lynne and Roy Wood with drummer Bev Bevan.  Their music is characterised by a fusion of Beatlesque pop, classical arrangements, and futuristic iconography.  After Wood's departure in 1972, Lynne became the band's leader, arranging and producing every album while writing virtually all of their original material. Hi!  School: Love On (Korean: 하이스쿨: 러브온 ) is a 2014 South Korean television series starring Kim Sae-ron, Nam Woo-hyun and Lee Sung-yeol of the band Infinite.  It aired on KBS2 from July 11 to December 19, 2014 on Fridays at 20:55 for 20 episodes. Wizzard were an English glam rock band formed by Roy Wood, former member of The Move and co-founder of the Electric Light Orchestra.  "The Guinness Book of 500 Number One Hits" states, "Wizzard was Roy Wood just as much as Wings were Paul McCartney."  They are most famous for their 1973 Christmas song "I Wish It Could Be Christmas Everyday". 'When Alice Comes Back to the Farm' is a rock-blues song recorded by The Move and written and sung by Roy Wood.  Musically, it is a hard rock song and features Wood playing slide guitar, cello and baritone saxophone reinforcing Rick Price's bassline. Nam Woo-hyun (Hangul: 남우현 ; Hanja: 南優賢 ; born February 8, 1991), commonly known by his mononym Woohyun, is a South Korean singer and actor with the boy band Infinite.  In 2016 he released a solo album. The Move are a British rock band of the late 1960s and the early 1970s.  They scored nine Top 20 UK singles in five years, but were among the most popular British bands not to find any real success in the United States.  Although bassist-vocalist Chris "Ace" Kefford was the original leader, for most of their career the Move was led by guitarist, singer and songwriter Roy Wood.  He wrote all the group's UK singles and, from 1968, also sang lead vocals on many songs, although Carl Wayne was the main lead singer up to 1970.  Initially, the band had 4 main vocalists (Wayne, Wood, Trevor Burton and Kefford) who split the lead vocals on a number of their earlier songs. Roy Wood's Helicopters was a band formed by Roy Wood and Renaissance bass guitarist Jon Camp in 1979, and consisted of Wood, Camp, guitarist Robin George, keyboard players Paul Robbins, Mike Deacon and drummer Kex Gorin.  The band was only used to play live shows (playing mainly songs Wood composed for The Move) and Wizzard, plus some of his solo singles and Jeff Lynne's "10538 Overture".  Terry Rowley and Tom Farnell joined the line-up for some of the live dates.
