Dalai Lama, 2015: After we reported his scheduled appearance at last year's Glastonbury, the event was removed from his website's calendar. It turned out to be true though, and Tenzin Gyatso not only appeared onstage on the festival's final day, but he was serenaded by Patti Smith to celebrate his birthday.
English Nationa Ballet, 2014: It was a brave decision to have the English National Ballet opening the Pyramid Stage last year... and it turned out to be a genius one. To commemorate the 100th anniversary of World War One, the group performed an incredibly moving dance, which focussed on the empowerment of women during the Great War. For once, a completely silent crowd was a very good sign indeed.
Tony Benn, 2012: The much-loved Labour socialist appeared regularly on Glastonbury's Left Field stage to give his unfettered opinions on the state of the world. When Benn died in 2014, the Left Field Tower was renamed the Benn Tower.
Tibetan Monks, 2013: The Dalai Lama's Tibetan monks must have enjoyed performing their Grammy-nominated chants at the festival in 2013, given that the big man himself is following in their footsteps two years on.
Matt Smith Orbital: The former Doctor Who joined the electronic dance duo onstage in 2010, 16 years after they played one of Glastonbury's most memorable sets. The team played a remix of Doctor Who's iconic theme-tune.
The Wombles, 2011: The cuddly, recycle-loving children's group drew a cult audience in 2011, many of whom were there in support after organiser Michael Eavis stated that booking them was "a mistake".
London Community Gospel Choir, 2010: The popular choir were an interesting alternative away from the likes of Snoop Dogg, Muse and Stevie Wonder in 2010 - even paying tribute to U2 who had to pull out of their headlining slot.
English National Opera, 2004: The first time in many years that the Glastonbury Town Band didn't open the festival, the ENO had a lot to live up to. Thankfully, a memorable performance of Wagner's 'Ride Of The Valkyries' more than proved their worth.
Emily Eavis, 1985; Yes, the Glasto co-organiser had her own moment in the spotlight almost three decades ago, when her Dad let her play a few songs on the violin at the tender age of 5. Clearly the attention didn't win her over - since then she's followed in her Dad's footsteps as one of the festival's chief organisers. We don't know if she still plays the violin.
Jeremy Corbyn, 2016: After his surprise ascension to the Labour leadership position last year, Corbyn has made good on his pledge to return the party to its left wing roots. At Glasto, he'll be speaking on behalf of the Campaign for Nuclear Disarmament. Of course.
