Problem: Background: Dafydd Rhys "Dave" Williams OC (born May 16, 1954) is a Canadian physician, public speaker and a retired CSA astronaut. Williams was a mission specialist on two space shuttle missions. His first spaceflight, STS-90 in 1998, was a 16-day mission aboard Space Shuttle Columbia dedicated to neuroscience research. His second flight, STS-118 in August 2007, was flown by Space Shuttle Endeavour to the International Space Station.
Context: In January 1995, Williams was selected to join the 1995 international class of NASA mission specialist astronaut candidates. He reported to the Johnson Space Center in March 1995 and completed training and evaluation in May 1996. On completing basic training, he was assigned to work technical issues for the payloads/habitability branch of the astronaut office. From July 1998 to November 2002, Williams served as Director of the Space and Life Sciences directorate with responsibility for research in both physical and biomedical space sciences at the Johnson Space Center (JSC). With this appointment, he became the first non-American to hold a senior management position within NASA. Overall crew medical safety was one of his principal concerns, in addition to flight medical operations and JSC occupational and environmental health. His programs were directed toward protecting astronauts from the hazards of the space environment, including space radiation and microgravity, in addition to maintaining their medical, physical, and psychological well-being while aloft and on return to Earth. His other oversight responsibilities were in the fields of telemedicine, 3-D tissue culture/regeneration in microgravity, the curatorial management of extraterrestrial materials, and of qualifying humans for very long space journeys and ensuring their safe return to Earth. Williams served as an aquanaut on the first NEEMO (NASA Extreme Environment Mission Operations) crew aboard the Aquarius underwater laboratory in October 2001. During this mission, he was thrilled to shake hands underwater with Canadian underwater explorer Joe MacInnis. Williams was originally scheduled to command NEEMO 7 in October 2004, but was replaced by back-up crewmember and fellow CSA astronaut Robert Thirsk due to Williams undergoing review of a temporary medical issue. In April 2006, Williams commanded the NEEMO 9 mission. During this eighteen-day mission, the six-person crew developed lunar surface exploration procedures and telemedical technology applications.

Problem: Background: Renaissance are an English progressive rock band, best known for their 1978 UK top 10 hit "Northern Lights" and progressive rock classics like "Carpet of the Sun", "Mother Russia", and "Ashes Are Burning". They developed a unique sound, combining a female lead vocal with a fusion of classical, folk, rock, and jazz influences. Characteristic elements of the Renaissance sound are Annie Haslam's wide vocal range, prominent piano accompaniment, orchestral arrangements, vocal harmonies, acoustic guitar, bass guitar, synthesiser, and versatile drum work. The band created a significant following in the northeast United States in the 70s, and that region remains their strongest fan base.
Context: As The Yardbirds were transforming into The New Yardbirds (with Jimmy Page) in 1968 and then Led Zeppelin, departing members Keith Relf and Jim McCarty formed an acoustic duo called Together. They released "Henry's Coming Home" b/w "Love Mum And Dad" as a single on Columbia Records in November 1968 without chart success. In January 1969, Relf and McCarty organised a new group devoted to experimentation with rock, folk, and classical forms. In his book Mountains come out of the sky: an illustrated history of prog rock, Will Romano quoted McCarty: This quintet -- Relf on guitar and vocals, McCarty on drums and vocals, plus bassist Louis Cennamo, pianist John Hawken, and Relf's sister Jane as an additional vocalist -- released a pair of albums on Elektra (US) and Island (UK-ILPS 9112), the first one, titled simply Renaissance, being produced by fellow ex-Yardbird Paul Samwell-Smith. The band had begun performing in May 1969, before recording had commenced for the debut LP, mostly in the UK, but with occasional forays abroad, including festivals in Belgium (Amougies, October 1969) and France (Operation 666 at the Olympia in January 1970, and Le Bourget in March 1970, both in Paris). In February 1970 they embarked on a North American tour, but that month-long trek proved only marginally successful. Because of their Yardbirds credentials, they found themselves paired with bands such as The Kinks and their new classically oriented direction did not always go down well because audiences were expecting rock/blues-based material. Beginning in the late spring of 1970 as touring began to grind on them, the original band gradually dissolved. Relf and McCarty decided to quit performing, and Cennamo joined Colosseum. Hawken organised a new line-up to fulfill contractual obligations to Island Records and complete the band's second album, Illusion which had been left unfinished.
Question: Did they have any influences?
Answer: they found themselves paired with bands such as The Kinks

Problem: Background: Steeleye Span are an English folk rock band formed in 1969. Still active today, along with Fairport Convention, they are amongst the best known acts of the British folk revival, and were among the most commercially successful, thanks to their hit singles "Gaudete" and "All Around My Hat". They had four Top 40 albums and achieved a certified gold record with sales of "All Around My Hat". Throughout their history, Steeleye Span have seen many personnel changes.
Context: Reported difficulties among band members saw a split during the recording of Bedlam Born. Woods reportedly was uncomfortable with the financial arrangements of the band, health problems forced Johnson into retirement, and drummer Dave Mattacks' period as an unofficial member came to an end during this time. For a while the band consisted of just Peter Knight and Tim Harries, plus various guest musicians, as they fulfilled live commitments. Rick Kemp resumed playing with the band at some of these gigs, with Harries switching to lead guitar. This was an uncertain time for the future of the band, and when Harries announced he was not keen to continue his role, even the willingness of Kemp to return to the line-up full-time was not enough to prevent what was effectively a break-up. In 2002, Steeleye Span reformed with a "classic" line-up (including Prior), bringing an end to the uncertainty of the previous couple of years. Knight hosted a poll on his website, asking the band's fans which Steeleye songs they would most want to see the band re-record. Armed with the results, Knight persuaded Prior and Genockey to rejoin, coaxed Johnson out of a health-induced retirement, and along with Kemp and Knight, they released Present--The Very Best of Steeleye Span (2002), a 2-disc set of new recordings of the songs. But Bob Johnson's health prevented him from playing live shortly before the 2002 comeback tour, and he was replaced at the eleventh hour on guitar by Ken Nicol, formerly of the Albion Band. Nicol had been talking with Rick Kemp about forming a band when Kemp invited him to play for the tour, and this was to herald a significant return to form for the band.
Question: When did they all reunite
Answer:
the 2002 comeback tour,
