Question:
Carlos Santana  audio  (born July 20, 1947) is a Mexican and American musician who first became famous in the late 1960s and early 1970s with his band, Santana, which pioneered a fusion of rock and Latin American jazz. The band's sound featured his melodic, blues-based guitar lines set against Latin and African rhythms featuring percussion instruments such as timbales and congas not generally heard in rock music. Santana continued to work in these forms over the following decades. He experienced a resurgence of popularity and critical acclaim in the late 1990s.
Carlos Santana's distinctive guitar tone is produced by PRS Santana signature guitars plugged into multiple amplifiers. The amps consist of a Mesa Boogie Mark I, Dumble Overdrive Reverb and more recently a Bludotone amplifier. Santana compares the tonal qualities of each amplifier to that of a singer producing head/nasal tones, chest tones, and belly tones. A three-way amp switcher is employed on Carlos's pedal board to enable him to switch between amps. Often the unique tones of each amplifier are blended together, complementing each other producing a richer tone.  He also put the "Boogie" in Mesa Boogie. Santana is credited with coining the popular Mesa amplifier name when he tried one and exclaimed, "That little thing really Boogies!"  Specifically, Santana combines a Mesa/Boogie Mark I head running through a Boogie cabinet with Altec 417-8H (or recently JBL E120s) speakers, and a Dumble Overdrive Reverb and/or a Dumble Overdrive Special running through a Brown or Marshall 4x12 cabinet with Celestion G12M "Greenback" speakers, depending on the desired sound. Shure KSM-32 microphones are used to pick up the sound, going to the PA. Additionally, a Fender Cyber-Twin Amp is mostly used at home.  During his early career Santana used a GMT transistor amplifier stack and a silverface Fender Twin. The GMT 226A rig was used at the Woodstock concert as well as during recording Santana's debut album. During this era Santana had also begun to use the Fender Twin, which was also used on the debut and proceedingly at the recording sessions of Abraxas.

input: During a tour of the U.S. Senate with reporters before leaving office, on December 5, 2016, Biden refused to rule out a potential bid for the Presidency in the 2020 presidential election, after leaving office as Vice President. If he were to run in 2020, Biden would be 77 years old on election day and 78 on inauguration day in 2021. He reasserted his ambivalence about running on an appearance of The Late Show with Stephen Colbert on December 7, in which he stated "never say never" about running for President in 2020, while also admitting he did not see a scenario in which he would run for office again. He seemingly announced on January 13, 2017, exactly one week prior to the expiration of his vice presidential term, that he would not run. However, four days later, on January 17, he seemed to backtrack, stating "I'll run if I can walk." A political action committee known as Time for Biden was formed in January 2018, seeking Biden's entry into the race.  In 2017, he was named the Benjamin Franklin Presidential Practice professor at the University of Pennsylvania, where he will focus on foreign policy, diplomacy, and national security while leading the Penn Biden Center for Diplomacy and Global Engagement. He will also pursue his "Cancer Moonshot" agenda. On March 12, 2017, Biden during a keynote speech at the annual SXSW festival stated, "The only bipartisan thing left in America is the fight against cancer."  On April 21, 2017, amidst speaking to a New York urban planning conference, Biden cited the "infinite wisdom" of Governor of New Jersey Chris Christie as the cause behind the termination of a rail tunnel project and called the Gateway Program "the most important infrastructure project in America."  During a Las Vegas, Nevada hedge fund conference interview on May 18, Biden said that he had never been confident in Clinton's candidacy: "I never thought she was a great candidate. I thought I was a great candidate."  Biden delivered a speech to the graduating class of Colby College on May 21, 2017, calling for a return to "unity and purpose", and three days later expressed confidence in contemporary students being able to handle "the challenges that lie ahead" at Harvard University during the college's Class Day ceremony.

Answer this question "what did Biden do in 2017?"
output: He seemingly announced on January 13, 2017, exactly one week prior to the expiration of his vice presidential term, that he would not run.

Answer the question at the end by quoting:

Supergrass were an English rock band, formed in 1993 in Oxford. The band consisted of brothers Gaz (guitar and lead vocals) and Rob Coombes (keyboards and backing vocals), Mick Quinn (bass and backing vocals) and Danny Goffey (drums and backing vocals). Originally a 3-piece, Gaz's brother Rob Coombes officially joined the band in 2002. The band signed to Parlophone records in 1994 and produced I Should Coco (1995), the biggest selling debut album for the label since the Beatles' Please
At the age of 16 and 18 respectively, Gaz Coombes and Danny Goffey were members of shoegaze band The Jennifers along with Nick Goffey and Andy Davis. The band played gigs at various venues around Oxfordshire, often public houses and clubs. One pub the band played at was the Jericho Tavern in Oxford. The band enjoyed enough success to release one single in 1992, "Just Got Back Today", on Nude Records before they disbanded.  When Coombes began working at the local Harvester he befriended co-worker Mick Quinn. The two realised they had common music interests and Coombes invited Quinn to come and jam with himself and Goffey. In February 1993 they formed Theodore Supergrass, "for about two months" Quinn explains, "then we realized that Theodore was a bit rubbish so we took that off."  Goffey claims that the name was his idea and says; "Although the others will dispute it, it was me. We were Theodore Supergrass and the idea was the band would be a little black character, and we wouldn't ever have to do interviews. We'd get the questions in advance, script the answers and then animate Theodore Supergrass answering them. But it cost too much money."  Gaz's brother, Rob Coombes, played flute for the band's debut gig at the Co-Op Hall, Oxford in 1993. In January 1995 he first performed as keyboardist with the band for a live Radio 1 John Peel session. His role in the band progressed over the years, post-I Should Coco material is credited to "Supergrass and Rob Coombes", however, he wasn't introduced as a band member until almost a decade later.

Was the band still together in 1993?
