Noel Gallagher is adamant that an Oasis reunion won't happen but with Liam at a loose end, following the split of Beady Eye, and Michael Eavis looking for a Glastonbury headliner, rumours of an Oasis reunion are ratcheting up a notch.
Here, we look at five bands who are well over due a festival defining reformation.
The White Stripes
This one is complicated. Jack and Meg White were married for four years up until 2000. They then divorced before becoming one of the biggest rock acts in the world, awkward!
Since they broke up in 2011, Meg has fallen off the face of the earth and Jack White has released a couple of decent blues-infused rock albums. However, nothing can quite compare to the garage-rock explosion of the White Stripes in their pomp. It has to happen.
Paul Weller said he'd have to be lying in the gutter before the Jam would reform but he has rekindled his relationship with bassist Bruce Foxton of late.
Weller, the front man and focal point, felt restrained by the Jam's guitar and rhythm section sound and the 'oi oi' nature of some of the scooter riding fans who followed The Jam around.
So, off he went and experimented with Jazz, piano pop,dance music and dodgy polo necks to mixed reviews with The Style Council in the 80s.
Just when it looked like the British record buying public's affection and patience for the Modfather had run out, he launched an acclaimed and commercially successful solo career while ignoring his old band mates.
Weller clearly doesn't need the money and the band probably went as far as they could musically before they split.
The sight of three men in their fifties pogo-ing around the stage to In the City'' might not be a good idea - but it would be hugely popular.
Morrissey has told fans to avoid buying Smiths albums because all the money "goes to that wretched drummer", following a court case taken by bassist Andy Rourke and drummer Mike Joyce in the 90s, that disputed the distribution of royalties between the four members of Manchester's most loved band.
Johnny Marr has been busy since the Smiths blew up in the late 80s with Electronic, The Healers and Modest Mouse, while Morrissey continues to subconsciously excite the homo-erotic side of many an adult man as a hugely successful solo artist.
However, fans of Manchester band's sound long for nothing more than to see Morrissey's brilliant lyrics married to Marr's unique guitar playing yet again - especially with the current economic climate as doom laden as the Smiths heyday.
It's not an impossibility, as the two have intermittently spoken in the last 25 years. The lead singer is not one for nostalgia though and his grudge bearing is legendary.
"I would rather eat my own testicles than reform The Smiths, and that's saying something for a vegetarian", he said in 2006.
Another, sadly, unlikely reunion.
When Oasis broke up in 2009, following an argument between Liam and Noel Gallagher, it felt like they would never get back on speaking terms.
The Manchester brothers had capitalised on the problems of The Stone Roses in the mid-nineties and forged ahead to become the biggest stadium rock group in the world. Their first two studio albums - Definitely Maybe and What's the Story Morning Glory, while not exactly breaking new musical ground, were refreshing, open, honest and well constructed rock LPs which justified the hype.
Then - as with most successful groups - drugs, alcohol, women and ego took over. What they released thereafter was - for the most part - regurgitated, tired music that was an effort to listen to. Still, they retained the affection of millions and fans flocked to watch them wherever they played with their denim jackets and Rod Stewart haircuts.
Following the split, Liam took the bassist and rhythm guitarist - whose names nobody can remember (except for Liam) - and formed the Oasis-lite tribute band Beady Eye, who changed the words to a couple of Oasis hits and threw in a few references to The Beatles and Stones.
Noel then surprised us all by releasing a half decent solo album that wasn't full to the brim of acoustic ballads about girls overdosing on Alka-Seltzer and doctors fornicating in helicopters.
Now, we all know that Liam and Noel are well 'ard and all that, but surely they will settle their differences and return to boring stadiums audiences 'all around the world' who are just waiting to hear 'Don't Look Back in Anger'.
They broke up in 1991 and have had two reFormations of sorts since then. In 1996 all the band's members except lead singer David Byrne got together for an album under the name 'The Heads'. In 2002 the full band performed three songs at their induction into the Rock and Roll Hall of Fame.
Byrne remains one of the most intriguing figures in alternative music and a reunion would be welcomed if it were to happen.
