Background: Robert Gordon Orr, OC (born March 20, 1948) is a Canadian former professional ice hockey player, widely acknowledged as one of the greatest hockey players of all time. Orr used his ice skating speed, scoring, and play-making abilities to revolutionize the position of defenceman. He played in the National Hockey League (NHL) for 12 seasons, starting with 10 with the Boston Bruins followed by two with the Chicago Black Hawks. Orr remains the only defenceman to have won the league scoring title with two Art Ross Trophies.
Context: Orr signed with Chicago, but his injuries limited him to only 26 games over the next three seasons. He sat out the entire 1977-78 season. By 1978, Orr had undergone over a dozen knee surgeries, was having trouble walking and barely skated anymore. However, in the summer of 1978, he decided to make a comeback. He played six games of the 1978-79 season and came to the conclusion that he could no longer play and informed the Black Hawks that he was retiring. He started a new role as an assistant to Chicago general manager Bob Pulford. He scored his last NHL goal and point against Detroit on October 28, 1978, at Detroit's Olympia Stadium.  Orr retired having scored 270 goals and 645 assists for 915 points in 657 games, adding 953 penalty minutes. At the time of his retirement, he was the leading defenceman in league history in goals, assists and points, tenth overall in assists and 19th in points. As of 2013, the only retired players in league history to have averaged more points per game than Orr are Wayne Gretzky, Mario Lemieux and Mike Bossy, all of them forwards. "Losing Bobby", said Gordie Howe, "was the greatest blow the National Hockey League has ever suffered".  The Hockey Hall of Fame waived the normal three-year waiting period for induction into the Hall and he was enshrined at age 31 - the youngest player living at the time of his induction in history. Orr was the eighth player to have the three-year period waived, the next two being Mario Lemieux (1997) and Wayne Gretzky (1999), after which the Hall decided that the waiting period would no longer be waived for any player except under "certain humanitarian circumstances".  His number 4 jersey was retired by the Bruins on January 9, 1979. At the ceremony, the crowd at Boston Garden would not stop applauding and as a result, most of the evening's program had to be scrapped at the last second due to the constant cheering. The crowd did not allow Orr to say his thank you speech until he put on a Bruins jersey. The day was proclaimed "Bobby Orr Day" in Boston and the event raised thousands of dollars for charity. He attended the Massachusetts Senate and House of Representatives and was given a five-minute standing ovation. Boston Celtics basketball superstar Larry Bird said in his pre-game inspiration that he always looked up at the rafters of the Garden at Orr's retired No. 4, instead of the retired numbers of Celtics stars such as Bill Russell, Bob Cousy, or John Havlicek.
Question: Why did they do that?
Answer: 

Background: 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. For their initial tenure, Lynne, Bevan and keyboardist Richard Tandy were the group's only consistent members.
Context: The success of the Children in Need was followed by much support from BBC Radio 2's DJ Chris Evans, who asked his listeners if they wanted ELO to perform. The 50,000 tickets for the resulting BBC Radio 2's "Festival in a Day" in Hyde Park on 14 September 2014 sold out in 15 minutes. Billed as "Jeff Lynne's ELO", Lynne and Tandy were backed by the Take That/Gary Barlow band from the Children in Need concert, led by Mike Stevens  and the BBC Concert Orchestra. The moniker came out from Lynne as a response to ELO tribute and imitation bands, (ELO Part II, the Orchestra, OrKestra and the Music of ELO) who repeatedly used ELO for promoting their own tours. Chereene Allen was the lead violinist for the band. The development of modern digital processing added a smoother finish to the work, which led Lynne to reconsider his preference for studio work, hinting at a UK tour in 2015.  On 8 February 2015, Jeff Lynne's ELO played at the Grammy Awards for the first time. They performed a medley of "Evil Woman" and "Mr. Blue Sky" with Ed Sheeran, who introduced them as "A man and a band who I love".  On 10 September 2015, it was announced that a new ELO album would be released. The album was to be under the moniker of Jeff Lynne's ELO, with the band signed to Columbia Records. Alone in the Universe was released on 13 November 2015. The album was ELO's first album of new material in nearly 15 years. The first track, and single, "When I Was a Boy" was made available for streaming on the same day and a music video for the song was also released. A small promotional tour followed the album's release which saw ELO perform a full concert for BBC Radio 2 along with ELO's first two shows in the United States in 30 years, both which sold out very quickly. ELO also made rare US television appearances on The Tonight Show Starring Jimmy Fallon, Jimmy Kimmel Live and CBS This Morning. Lynne was joined by Traveling Wilbury's photographer Nick J (NJ Latham) for a 19-date European tour that was announced for 2016, with the band playing the Pyramid Stage at Glastonbury Festival on 26 June 2016.  In 2017 they played their "Alone in the Universe" tour. In 2017 they played at the Rock and Roll Hall of Fame during the 32nd Annual Induction Ceremony.
Question: Did anything big happen in that tour?
Answer:
with the band playing the Pyramid Stage at Glastonbury Festival on 26 June 2016.
