Answer the question at the end by quoting:

Deep Purple are an English rock band formed in Hertford in 1968. The band is considered to be among the pioneers of heavy metal and modern hard rock, although their musical approach changed over the years. Originally formed as a progressive rock band, the band shifted to a heavier sound in 1970. Deep Purple, together with Led Zeppelin and Black Sabbath, have been referred to as the "unholy trinity of British hard rock and heavy metal in the early to mid-seventies".
The end came on tour in England on 15 March 1976 at the Liverpool Empire Theatre. In the words of Jon Lord:  "At one point during the show, Glenn said to the audience, 'I'm sorry we're not playing very well, but we're very tired and jet-lagged.' And I remember spluttering to myself, 'Speak for yourself.' I was working like a Trojan to try and make this work ... Paicey was playing like a madman just to keep it all together ... Coverdale was singing his socks off. So to hear this guy who was extremely high on various substances telling the audience, 'I'm sorry, We aren't playing well' kind of rankled me a bit. I came off stage and went straight to my dressing room, which I was sharing with Ian Paice, and I said, 'Ian ... that's it, isn't it? That's absolutely the end of this band as far as I'm concerned. Why are we doing this to ourselves?' So he and I shook hands and said, 'It's over. Thank God.' About ten minutes later, Coverdale came in, big blustery guy that he is, and he said, 'I'm leaving the band!' And we said, 'David, there's no band to leave.'"  The break-up was finally made public in July 1976, with then-manager Rob Cooksey issuing the simple statement: "the band will not record or perform together as Deep Purple again". Later in the year, Bolin had just finished recording his second solo album, Private Eyes, when, on 4 December 1976, tragedy struck. In a Miami hotel room, during a tour supporting Jeff Beck, Bolin was found unconscious by his girlfriend and bandmates. Unable to wake him, she hurriedly called paramedics, but it was too late. The official cause of death was multiple-drug intoxication. Bolin was 25 years old.  After the break-up, most of the past and present members of Deep Purple went on to have considerable success in a number of other bands, including Gillan, Whitesnake and Rainbow. There were, however, a number of promoter-led attempts to get the band to reform, especially with the revival of the hard rock market in the late 1970s and early 1980s. In 1980, a touring version of the band surfaced with Rod Evans as the only member who had ever been in Deep Purple, eventually ending in successful legal action from the legitimate Deep Purple camp over unauthorised use of the name. Evans was ordered to pay damages of US$672,000 for using the band name without permission.

Why did the band split up?

Glenn said to the audience, 'I'm sorry we're not playing very well, but we're very tired and jet-lagged.' And I remember spluttering to myself, 'Speak for yourself.'

IN: CBC Radio 3 is a radio network that consists of two parts devoted to Canadian arts and music: a radio service which is available on Sirius XM Satellite Radio and streaming audio, and several daily and weekly podcasts from the CBC Radio 3 website. The audio stream is available from both CBC Music and from iTunes Radio, but geographical restrictions are in place to prevent access outside of Canada. The network evolved out of programming on CBC Radio 2, which also simulcasted the satellite network on Saturday and Sunday nights from its debut in December 2005 until March 17, 2007. Radio 3 is no longer heard on terrestrial radio, but is still available through its satellite radio and Internet operations.

On April 20, 2007, as part of CBC Radio 3's 100th podcast, a weekly video podcast was introduced. The new video-based podcast, R3TV, revolved around the personalities at CBC Radio 3 and featured a particular artist each week, who provided commentary for the podcast and had their music videos featured in the show. R3TV was also available as a channel on Internet television services such as Joost, YouTube and Miro Media Player.  In 2011, CBC Radio 3 sponsored its first documentary movie, Winning America, about Canadian band Said the Whale. The movie was directed by Brent Hodge and Thomas Buchan, and produced by Jon Siddall, Brent Hodge and Sheila Peacock. It first aired on July 23, 2011 on CBC Television in British Columbia, and then nationally on April 2, 2012.  After the success of the first film, Radio 3 decided to do a second documentary movie called What Happens Next? about Canadian musician Dan Mangan. This movie was produced and directed by Brent Hodge and Jon Siddall. It aired on CBC on August 25, 2012 in BC, and then again nationally on October 20, 2012.  Radio 3's next foray into video was in 2013, with the web series The Beetle Roadtrip Sessions. It followed host Grant Lawrence across Canada visiting various musicians and other personalities along the way, including The Darcys, Hollerado, Sam Roberts, Theo Fleury, Hawksley Workman and others. It was also directed by Brent Hodge. The Beetle Roadtrip Sessions won the award for Best Original Program or Series produced for Digital Media - Non-Fiction at the 2nd Canadian Screen Awards.
