The two musicians reunited on Thursday (16.02.17) in London to launch the upcoming 'Pink Floyd Exhibition: Their Mortal Remains' and were quizzed on whether or not one more great gig beckoned for the psychedelic legends at Michael Eavis' world famous festival, which they never played at as a band.
Roger quit the group back in 1985 citing Pink Floyd as a ''spent force creatively'' and since has only performed with Nick and the other surviving member David Gilmour back in 2005 at the Live 8 charity concert in London, and during Waters' performance of 'The Wall' at The O2 arena in 2011 on a rendition of 'Comfortably Numb'.
Despite the clamour from fans, he he has no interest in playing at Pilton Farm in Somerset, South West England, under the Pink Floyd banner but is keen to do so as a solo artist.
Speaking during a Q&A session, Roger said: ''I did Glastonbury once, I think. It was really cold. But there were a lot of people and it seemed very jolly and I liked it. Yeah, I would do it again.''
Speaking about his unfulfilled ambition to top the bill on the Pyramid Stage, Nick, 73, said: ''It would be nice to add it to the list of things. I've never played Glastonbury. It would be fun to do it. I don't think it would be very likely.''
The pair also seemed to think that 70-year-old David's semi-retirement status would be a stumbling block to any Glastonbury performance for Pink Floyd.
Roger said: ''The last I heard, David had retired.''
Nick then quipped back: ''I heard he retired, then he seemed to un-retire.''
Roger, 73, admits he is tired of people asking him if Pink Floyd - whose keyboard player Rick Wright passed away in 2008 at the age of 65 - will ever get back together as he's as focused as ever on his solo career, with a new album coming this year.
The LP is called 'Is This The Life We Really Want?' and it's getting close to completion.
Referring to the chances of a full reunion, the 'Another Brick In The Wall' singer said: ''People ask all the time. It's boring isn't it?''
Then discussing his next record, he added: ''I'm just in the process of finishing my new album. I finished the vocals yesterday and Nigel Godrich who is producing it has begun mixing it. It's called 'Is This The Life You Really Want?' and I'm going on the road this summer, taking a tour called 'Us And Them', around America and then around the world throughout 2018.''
'The Pink Floyd Exhibition: Their Mortal Remains' runs at the V&A Museum in London from May 13 to October 1.
