DJ Derek, whose real name is Derek Morris, also appeared at the Big Chill and numerous gigs across the UK. Avon and Somerset Police confirmed Mr Morris was reported missing on Thursday and a search for him is under way. Mr Morris's niece, Jennifer Amy, said his disappearance is "completely out of character". She said: "I've left numerous messages for him and he hasn't got back - if he goes away he always lets me know. "His friends have been in touch to say he hasn't been in contact. "We're all extremely worried." And Bristol's elected mayor, George Ferguson, said on Twitter: "DJ Derek is a legend - I'll do all I can to spread word across #Bristol." Geoff Barrow, from the band Portishead, has also tweeted his support while Bestival founder and DJ Rob da Bank hoped one of his "favourite ever" DJs would be found. DJ Derek's disappearance is trending on the social networking site. Mr Morris launched his DJ Derek career in his mid-30s after working in the accounts department of confectionery firm Cadbury's. In 2006, he told the BBC's Inside Out that he left the firm after years of "domestic hell" before starting work as a DJ in a Bristol pub. Over more than 40 years he established himself as a fixture on the city's clubbing scene. As well as playing at Glastonbury, he has also released his own compilation album and appeared in a Dizzee Rascal video. In 2012 he won the Lord Mayor's medal for his "outstanding" contribution to the music scene in the city. Speaking to BBC Radio 4 after he was given the award, he said he finished most sets with the Bob Marley classic One Love. He said: "It's a perfect signing-off record for a reggae set - let's get together and feel all right. So next time, people, let's get together and feel all right." He played his final set before retiring at a London show in 2013.
A 73-year-old DJ who played sets at Glastonbury has gone missing, his family has said.

Sunday's test took place underground at the mountainous Punggye-ri site. Analysis group 38 North published pictures which show "more numerous and widespread" disturbances than before. The test unleashed a powerful 6.3-magnitude tremor which was felt across the border in China. North Korea has conducted six nuclear tests so far, all at Punggye-ri, which consists of a system of tunnels dug beneath a mountainous region. 38 North said its latest pictures, which were taken a day after the latest test, showed landslides as well as numerous areas of gravel and scree fields which were "lofted" from the tremors. Lofting occurs when shockwaves force material to be lifted up from the ground, and the material falls back down in the same place. The disturbances took place near Mount Mantap, the highest point in the test site. They were "more numerous and widespread than what we have seen from any of the five tests North Korea previously conducted", the site's analysis said. But it added that while the test triggered a powerful tremor, it did not appear to have caused the crater to collapse. Some experts believe however that the nuclear test did cause an underground tunnel at Punggye-ri to collapse. Sunday's bomb was thought to have had a power range from 50 to 120 kilotonnes. A 50kt device would be about three times the size of the US bomb that destroyed Hiroshima in 1945. The repeated tests have prompted concerns about the test site's longevity, although experts are divided. Earlier this week Chinese scientists warned of the possibility of the mountain caving in and releasing radiation after future tests, reported the South China Morning Post. A previous 38 North commentary debunked the possibility of the tests triggering a volcanic eruption.
North Korea's recent nuclear test appears to have triggered several landslides, according to what are believed to be the first satellite images of the aftermath.
